This article discusses a rare genetic disorder called hereditary fibrosing poikiloderma (HFP) that affects two siblings. HFP is characterized by childhood poikiloderma, muscle contractures, and pulmonary fibrotic defects. The siblings presented with pigmented cheek rash, eczematous lesions, and recurrent skin and ear infections. Genetic testing revealed a novel variation in the FAM111B gene, confirming a diagnosis of HFP. Treatment includes prophylactic antibiotics, photoprotection, and vitamin D supplementation. The article also explores the differential diagnoses and management approaches for HFP. [Extracted from the article]

Summary: Poikiloderma with neutropenia (PN) Clericuzio type (OMIM #604173) is a rare disease with areas of skin hyper‐ and hypopigmentation caused by biallelic USB1 variants. The current study was spurred by poor healing of a perianal tear wound in one affected child homozygous for c.266‐1G>A (p.E90Sfster8) mutation, from a family reported previously. Treatment with G‐CSF/CSF3 or GM‐CSF/CSF2 transiently increased neutrophil/monocytes count with no effect on wound healing. Analysis of peripheral blood revealed a lack of non‐classical (CD14+/−CD16+) monocytes, associated with a systemic inflammatory cytokine profile, in the two affected brothers. Importantly, despite normal expression of cognate receptors, monocytes from PN patients did not respond to M‐CSF or IL‐34 in vitro, as determined by cytokine secretion or CD16 expression. RNAseq of monocytes showed 293 differentially expressed genes, including significant downregulation of GATA2, AKAP6 and PDE4DIP that are associated with leucocyte differentiation and cyclic adenosine monophosphate (cAMP) signalling. Notably, the plasma cAMP was significantly low in the PN patients. Our study revealed a novel association of PN with a lack of non‐classical monocyte population. The defects in monocyte plasticity may contribute to disease manifestations in PN and a defective cAMP signalling may be the primary effect of the splicing errors caused by USB1 mutation.

Rothmund-Thomson syndrome (RTS), also known as congenital poikiloderma, is a genodermatosis that appears in infancy and is characterized by poikilodermatous changes in the skin. It is a very rare and complex genetic disorder that can present with a wide range of symptoms and affect multiple systems in the body. The syndrome is inherited in an autosomal recessive manner. A 21-year-old female patient presented to our rheumatology outpatient clinic with swelling of the hands, sclerodactyly, and stiffness of the fingers with preliminary diagnosis of systemic sclerosis. She has had deformities in her feet and hands since the age of one year. Physical examination revealed poikiloderma and extremity deformities. She also had neutropenia in her bloodstream. She was diagnosed with Rothmund Thomson syndrome after genetic test results, prescribed colchicine and followed up regularly every three months. After two years of follow-up, she was diagnosed with ovarian cancer. [ABSTRACT FROM AUTHOR]

Acrogeria is a rare, nonhereditary genetic syndrome that presents with nonprogressive atrophy of the skin of the distal extremities, giving it an aged appearance. The patients have characteristic facies with pinched faces, an "owl-eyed" appearance, and a beaked nose. We report a 14-year-old female patient of acrogeria who presented with typical clinical findings and dermoscopic features. Acrogeria, with onset usually at birth or thereafter, is often sporadic with potential genetic underpinnings. Uncommon features encompass skeletal and soft-tissue anomalies. The prognosis is generally favorable for these patients due to the lack of systemic involvement. To the best of our knowledge, dermoscopic features of acrogeria have not been described previously. We report this case owing to its rarity and to describe the dermoscopic features seen in this rare syndrome. [ABSTRACT FROM AUTHOR]

Background: Mutations of the human FAM111B gene are associated with hereditary fibrosing poikiloderma with tendon contracture, myopathy, and pulmonary fibrosis (POIKTMP), a rare and autosomal dominant multi-systemic fibrosing disease. To date, a total of 36 cases are documented, with eleven associated mutations identified and confirmed by Whole-Exome Sequencing and Sanger sequencing. However, these methods require a certain level of expertise. The FAM111B gene was annotated using the SNAPGENE tool to identify various restriction enzymes. The enzymes that cut at the positions where mutations of interest have been reported were selected. The method was implemented using the DNA samples extracted from the skin fibroblast collected from an affected South African family and unrelated control. Results: The findings showed that of the eleven FAM111B mutational sites investigated with this method, ten mutations can be identified including the known mutation FAM111B NM_198947.4: c.1861T>G (pTyr621Asp) associated with the POIKTMP in South Africa. Conclusions: Limited access to molecular diagnosis contributes to why POIKTMP is rarely diagnosed. Our study describes an inexpensive PCR–RFLP method to screen for POIKTMP FAM111B gene mutations. The PCR–RFLP can be used as a cost-effective method for diagnosing FAM111B mutations in POIKTMP, and it does not require having robust experience in molecular biology. [ABSTRACT FROM AUTHOR]

Mutations in the human FAM111B gene are associated with a rare, hereditary multi‐systemic fibrosing disease, POIKTMP. To date, there are ten POIKTMP‐associated FAM111B gene mutations reported in thirty‐six patients from five families globally. To investigate the clinical significance of these mutations, we summarized individual cases by clinical features and position of the reported FAM111B gene mutations as those within and outside the putative protease domain (MWPPD and MOPPD respectively). MWPPD cases had more clinical manifestations than MOPPD (25 versus 18). Although the most common clinical features of poikiloderma, alopecia and hypohidrosis overall occurred in 94%, 86% and 75% of all cases with no significant differences between the MOPPD and MWPPD group, less common features included life‐threatening (pulmonary fibrosis 47% vs. 13%; liver abnormalities specifically cirrhosis 26% vs. 7%) and physically disabling conditions (myopathy 53% vs. 20%; tendon contracture 55% vs. 7%) were more common in MWPPD cases. Similarly, the only 2 cases of POIKTMP with fatal pancreatic cancers were both only in the MWPPD group. This review thus suggests that mutations within the putative protease domain of the FAM111B protein are associated with a broader range of clinical features and may predict increased POIKTMP severity and a poorer prognosis.

Background: Rothmund-Thomson syndrome (RTS) is an autosomal recessive genetic disorder characterized by poikiloderma of the face, small stature, sparse scalp hair, juvenile cataract, radial aplasia, and predisposition to cancers. Due to the rarity of RTS, the situation of patients with RTS in Japan has not been elucidated. Methods: In 2010 and 2020, following the results of a primary questionnaire survey, a secondary questionnaire survey on RTS was conducted nationwide to investigate the number of RTS cases and their associated skin lesions, bone lesions, other clinical features, and quality of life in Japan. Results: In 2010 and 2020, 10 and eight patients with RTS were recruited, respectively. Skin lesions such as poikiloderma, erythema, pigmentation, and abnormal scalp hair were observed in almost all cases. Bone lesions were observed in four cases in the 2010 and 2020 surveys, respectively. Two cases had mutations in the RECQL4 gene in the 2020 survey. Conclusions: Two nationwide surveys have shown the actual situation of patients with RTS in Japan. Cutaneous and bone manifestations are important for the diagnosis of RTS. However, many patients have no RECQL4 mutations. The novel causative gene of RTS should be further elucidated. [ABSTRACT FROM AUTHOR]

Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive disorder caused by homozygous or compound heterozygous mutations in RECQL4 gene and has characteristic clinical features of poikiloderma, congenital bone defects, gastrointestinal disturbances such as chronic diarrhea and vomiting, and an increased susceptibility to malignancy. A 2½-year-old Indian boy presented with reticulate hyperpigmented erythema with superimposed hypopigmented atrophic macular lesions over the cheeks and diffuse background hyperpigmentation with multiple discrete atrophic hypopigmented macules of variable size over the abdomen and extensor aspects of the forearms. X-rays suggested metaphyseal irregularity around knee joint and radioulnar synostosis. Whole-exome sequencing was suggestive of a de novo novel RECQL4 gene mutation causing RTS Type II. There is an overlapping of clinical features of the group of syndrome associated with skin lesions, skeletal, and gastric manifestations. All these conditions present a challenge to the clinician. Thus, molecular diagnosis is the only way to resolve these phenotypically similar conditions. This report expands the RECQL4 gene pathogenic mutations spectrum. [ABSTRACT FROM AUTHOR]

There are various causes of childhood poikiloderma. A proper history and clinical examination may help to get conclusion and narrow down the differentials for the causes of poikiloderma. [ABSTRACT FROM AUTHOR]

Rothmund-Thomson syndrome (RTS) is an autosomal-recessive disorder characterized by poikiloderma, sparse hair, short stature, and skeletal anomalies. Type 2 RTS, which is defined by the presence of bi-allelic mutations in RECQL4 , is characterized by increased cancer susceptibility and skeletal anomalies, whereas the genetic basis of RTS type 1, which is associated with juvenile cataracts, is unknown. We studied ten individuals, from seven families, who had RTS type 1 and identified a deep intronic splicing mutation of the ANAPC1 gene, a component of the anaphase-promoting complex/cyclosome (APC/C), in all affected individuals, either in the homozygous state or in trans with another mutation. Fibroblast studies showed that the intronic mutation causes the activation of a 95 bp pseudoexon, leading to mRNAs with premature termination codons and nonsense-mediated decay, decreased ANAPC1 protein levels, and prolongation of interphase. Interestingly, mice that were heterozygous for a knockout mutation have an increased incidence of cataracts. Our results demonstrate that deficiency in the APC/C is a cause of RTS type 1 and suggest a possible link between the APC/C and RECQL4 helicase because both proteins are involved in DNA repair and replication.

Poikiloderma is a hereditary pathologic situation in which the appearance of skin rash is associated with epidermal atrophy, telangiectasia, and reticular dyspigmentation skin symptoms of poikiloderma are usually caused by sun damage. The main reason forpoikiloderma is unknown. We introduce a 14-month-old boy who referred to our center with a complaint of fever and cough. Furthermore, hepatosplenomegaly symptoms had been presented at the time of birth and were continuously observed at age one. He had transient thrombocytopenia when he was born due to his prematurity condition, which was resolved during Intravenous Immunoglobin (IVIG) treatment. Therefore, the presence of various mutation scan lead to distinct clinical symptoms. Immunohematologic abnormalities such as increased level of IgM and IgE antibodies, as well as increased C-reactive protein (CRP) and Erythrocyte sedimentation rate (ESR), have been reported. However, mutation of the C16orf57 gene was identified in this patient. We also introduced a new genetic mutation in a particular part of DNA sequence (NM_001195302: exon6: c.T703C) that leads to new clinical finding in PN. [ABSTRACT FROM AUTHOR]

Abstract Clericuzio-type poikiloderma with neutropenia is a well-defined nosological entity, but despite a remarkable number of clinical reports, no long term follow-up data has been presented to date regarding patients with this rare condition. Here we describe the results of clinical follow-up of three siblings, one male (Patient 1) and two females (Patients 2 and 3), subsequent to their first clinical and then molecular diagnosis of Clericuzio-type poikiloderma with neutropenia syndrome due to mutation of USB1 gene. Patient 1 always expressed the most severe phenotype, while patients 2 and 3 showed an intermediate and mild phenotype, respectively, as observed since their first clinical evaluation. None of the patients developed skin cancer and/or myelodysplastic disorders considering the peripheral haematological findings. Lens opacity, never reported before, was found in two of the three patients. The long term follow-up observations confirm the stability over time of the pronounced intra-familial heterogeneity of clinical manifestations observed prior to and upon molecular diagnosis. We conclude that prolonged follow-up is an adjunct tool to monitor intra-familial variability of PN clinical spectrum which may favour surveillance of more serious complications of the disease among siblings, when a patient-specific clinical expressivity is present.

Poikiloderma is characterized by mottled pigmentation, telangiectasia, and epidermal atrophy. It is a common cutaneous finding in a number of genodermatoses. We present a case of a 13-month-old male child with poikiloderma, heat intolerance, and photosensitivity, which made us evaluate him for poikiloderma-associated syndromes. The diagnosis of Hereditary Fibrosing Poikiloderma (HFP) was done based on the genetic study which showed mutation in FAM 111B gene. [ABSTRACT FROM AUTHOR]

Rothmund-Thomson syndrome (RTS) is characterized by poikiloderma, sparse hair, eyelashes, and/or eyebrows, small stature, skeletal and dental abnormalities, cataracts and an increased risk of cancer, especially osteosarcoma. Authors describe a case of 35 year old man with poikiloderma, universal alopecia and anaplastic large T-cell lymphoma (ALCL). The skin manifestation first appeared at age of 23 years of the patient. Diagnosis of RTS was based on the clinical manifestation and genetic examination, that showed RECQ4 mutations presented at multiple levels. Sequencing of fibroblasts by Western blot analysis confirmed Gln253His mutation typical for RTS. Despite combined chemotherapy of ALCL the patient died 17 days after its initiation due to cardiac arrest. RTS is a rare genodermatosis. Because of increased risk of skin cancer, follow-up of patients with RTS is mandatory. [ABSTRACT FROM AUTHOR]

We present a patient with poikiloderma, severe osteoporosis and a mild intellectual disability. At the age of 9 years, this patient was proposed to suffer from a novel disease entity designated as calcinosis cutis, osteoma cutis, poikiloderma and skeletal abnormalities (COPS) syndrome. At the age of 35, he was diagnosed with Hodgkin's lymphoma. Recently, biallelic pathogenic variants in the RECQL4 gene were detected (c.1048_1049delAG and c.1391-1G>A), confirming a diagnosis of Rothmund-Thomson syndrome (RTS). In the brother of this patient, who had a milder phenotype, a similar diagnosis was made.Conclusion: We conclude that COPS syndrome never existed as a separate syndrome entity. Instead, osteoma cutis may be regarded as a novel feature of RTS, whereas mild intellectual disability and lymphoma may be underreported parts of the phenotype. What is new: • Osteoma cutis was not a known feature in Rothmund-Thomson patients. • Intellectual disability may be considered a rare feature in RTS; more study is needed. What is known: • RTS is a well-described syndrome caused by mutations in the RECQL4 gene. • Patients with RTS frequently show chromosomal abnormalities like, e.g. mosaic trisomy 8.

Rothmund–Thomson syndrome is a rare, autosomal recessive genodermatosis characterized by an early-onset poikiloderma, skeletal abnormalities, short stature, premature aging, and increased susceptibility to malignancy. We report a case of a 1-year-old male child with bullous lesions and pigmentary changes over the face and extremities. Strict photoprotection and careful surveillance for malignancy forms the mainstay of treatment. The case is being reported due to its rarity and the diagnostic dilemmas associated with it.

Kindler's syndrome (KS) is a rare inherited skin disease characterized by acral blistering, photosensitivity, progressive poikiloderma, and cutaneous atrophy along with different types of mucosal involvement. We hereby report KS in two siblings. The case is being reported for its rarity and for emphasizing the importance of considering this condition in the differential diagnosis of disorders that may cause blistering, cutaneous atrophy, and/or poikilodermatous skin changes. Besides, the presentation of the disease in two of the members of the same family makes the case even more interesting. [ABSTRACT FROM AUTHOR]

Background: Hereditary Fibrosing Poikiloderma (HFP) with tendon contractures, myopathy and pulmonary fibrosis (POIKTMP [MIM 615704]) is a very recently described entity of syndromic inherited poikiloderma. Previously by using whole exome sequencing in five families, we identified the causative gene, FAM111B (NM_198947.3), the function of which is still unknown. Our objective in this study was to better define the specific features of POIKTMP through a larger series of patients.Methods: Clinical and molecular data of two families and eight independent sporadic cases, including six new cases, were collected.Results: Key features consist of: (i) early-onset poikiloderma, hypotrichosis and hypohidrosis; (ii) multiple contractures, in particular triceps surae muscle contractures; (iii) diffuse progressive muscular weakness; (iv) pulmonary fibrosis in adulthood and (v) other features including exocrine pancreatic insufficiency, liver impairment and growth retardation. Muscle magnetic resonance imaging was informative and showed muscle atrophy and fatty infiltration. Histological examination of skeletal muscle revealed extensive fibroadipose tissue infiltration. Microscopy of the skin showed a scleroderma-like aspect with fibrosis and alterations of the elastic network. FAM111B gene analysis identified five different missense variants (two recurrent mutations were found respectively in three and four independent families). All the mutations were predicted to localize in the trypsin-like cysteine/serine peptidase domain of the protein. We suggest gain-of-function or dominant-negative mutations resulting in FAM111B enzymatic activity changes.Conclusions: HFP with tendon contractures, myopathy and pulmonary fibrosis, is a multisystemic disorder due to autosomal dominant FAM111B mutations. Future functional studies will help in understanding the specific pathological process of this fibrosing disorder. [ABSTRACT FROM AUTHOR]

Rothmund-Thomson syndrome (RTS; MIM#268400) is an autosomal recessive genodermatosis with <500 cases described in the literature [1]. About 60% of RTS cases carry biallelic pathogenic variants in the RECQL4 gene representing the prevalent RTS subentity (RTS-2) [1]. RTS-2 is characterized by poikiloderma manifesting in the first months of life on photo-exposed areas, short stature, sparse hair, eyelashes and/or eyebrows, skeletal abnormalities, and predisposition to malignancy [1]. Endocrine signs may be present and subfertility is common; however, a few patients have had healthy offspring [2-3]. [ABSTRACT FROM AUTHOR]

Three overlapping conditions, namely Rothmund-Thomson ( RTS), Baller-Gerold ( BGS) and RAPADILINO syndromes, have been attributed to RECQL4 mutations. Differential diagnoses depend on the clinical presentation, but the numbers of known genes remain low, leading to the widespread prescription of RECQL4 sequencing. The aim of our study was therefore to determine the best clinical indicators for the presence of RECQL4 mutations in a series of 39 patients referred for RECQL4 molecular analysis and belonging to the RTS (27 cases) and BGS (12 cases) spectrum. One or two deleterious RECQL4 mutations were found in 10/27 patients referred for RTS diagnosis. Clinical and molecular reevaluation led to a different diagnosis in 7/17 negative cases, including Clericuzio-type poikiloderma with neutropenia, hereditary sclerosing poikiloderma, and craniosynostosis/anal anomalies/porokeratosis. No RECQL4 mutations were found in the BGS group without poikiloderma, confirming that RECQL4 sequencing was not indicated in this phenotype. One chromosomal abnormality and one TWIST mutation was found in this cohort. This study highlights the search for differential diagnoses before the prescription of RECQL4 sequencing in this clinically heterogeneous group. The combination of clinically defined subgroups and next-generation sequencing will hopefully bring to light new molecular bases of syndromes with poikiloderma, as well as BGS without poikiloderma.

Huriez syndrome is a rare autosomal dominant genodermatosis characterized by the triad of congenital scleroatrophy of the distal extremities, palmoplantar keratoderma (PPK) and hypoplastic nails. We report the case of a 25 year old male, with nonfamilial Huriez syndrome. [ABSTRACT FROM AUTHOR]

Rothmund-Thomson syndrome (RTS) is a genodermatosis presenting with a characteristic facial rash (poikiloderma) associated with short stature, sparse scalp hair, sparse or absent eyelashes and/or eyebrows, juvenile cataracts, skeletal abnormalities, radial ray defects, premature aging and a predisposition to cancer. RTS also present dental abnormalities like malformation: microdontia and failure of eruption. We report an unusual patient with Rothmund-Thomson syndrome (RTS), a genodermatosis. The patient is 19 year old with poikiloderma, skeletal abnormalities and dental abnormalities. In this case report evaluation of the various abnormality of the patient has been reviewed.

A 70-year-old woman presented with generalized reticulate pigmentation, scarring alopecia, and few discrete, violaceous plaques over the trunk and forearm. Dermoscopic evaluation of the reticulate plaque showed reticulate hyperpigmentation with multiple telangiectasias, and skin biopsy showed lichenoid interface dermatitis with marked pigment incontinence. Thus, a final diagnosis of poikiloderma due to lichen planus pigmentosus was considered. [ABSTRACT FROM AUTHOR]

Kindler syndrome is a rare genodermatosis with autosomal recessive inheritance and less than 150 cases reported worldwide. It results from loss of function mutation in the KIND1 gene (FERMT1), which has been localized to the short arm of chromosome 20. Onset is just after birth with traumatic blistering healing without scarring, skin fragility, progressive poikiloderma and photosensitivity improving with age. Systemic complications and fatally aggressive squamous cell carcinoma have also been reported. Here, we report a case with classic dermatologic manifestations in an 8-year-old female along with a brief review of literature. [ABSTRACT FROM AUTHOR]

Introduction: Dermatomyositis is an idiopathic inflammatory myopathy. It is a systemic disorder that most frequently affects the skin and muscles, but may also affect the joints, the esophagus, the lungs, and, less commonly, the heart. Case report: It is presented with characteristic cutaneous findings like skin rash as well as progressive symmetrical proximal muscle weakness. Its prevalence rate is approximately one per 100,000 in the general population with a female to male predominance of about 2:1. Conclusion: We report a male patient with the classical features of dermatomyositis in whom cutaneous changes preceded muscle weakness. [ABSTRACT FROM AUTHOR]

Mycosis fungoides (MF) represents the most common type of cutaneous lyrnphoma. MF shows varieties in both its clinical presentation and immunophenotype. We herein report one case of poikilodermatous MF with a CD8+ CD56+ immunophenotype and present a literature review. A 20-year-oldJapanese woman presented with a 10-year history of multiple poikilodermatous and reddish or brownish patches with mild pruritus on the chest, abdomen, back, buttock and thighs. Histopathologically, small- to medium-sized atypical lymphocytes infiltrated into the epidermis, indicating epidermotropism, along the basal layer, and distributed in band-like appearance in the papillary dermis. Immunohistochemically, atypical lymphocytes expressed CD3, CD8, CD56, T-cell intracellular antigen (TIA)-1, granzyme B and beta Fl but lacked expression of CD4-, CD20, CD3O and Epstein-Barr virus (EBV) latent membrane protein 1. An EBV-encoded small non-polyadenylated RNA-1 (EBER-l) signal was not detected. On the basis of these findings, the diagnosis of CD8+ CD56+ MF was established. Poikiodermatous MF with a CD8+ CD56+ immunophenotype, as presented herein, is extremely rare. Although further investigation is needed to fully clarify the nature of this aberrant phenotype of MF, we stress that it is important to recognize this rare immunophenotype of MF to distinguish it from aggressive cytotoxic cutaneous lymphomas.

Background: Rothmund-Thomson syndrome is a rare autosomal recessivegenodermatosis characterized by early onset of poikiloderma and several other cutaneous and organ involvements. Case Report: We are going toreport a 14-year-old girl who has been diagnosed with Rothmund- Thomson syndrome since she was 3 years old and has been suffering from pain and swelling of thright elbow and forearm for about 6 months. She was admitted because of a swelled tender erythematous mass on her right elbow that had appeared one year ago and enlarged gradually. On physical examination, she had a bird-like appearance. Scalp hair, eyebrows and lashes was sparse. Findings: There are few previous reports on Rothmund-Thomson syndrome associated with malignant fibrous histiocytoma. Conclusion: We decidedto report this case as another supporting document for this association. [ABSTRACT FROM AUTHOR]

Abstract: Poikiloderma occurs in a number of hereditary syndromes, the best known of which is Rothmund–Thomson syndrome (RTS). Differential diagnoses include Dyskeratosis Congenita (DC) with high genetic heterogeneity and Clericuzio-type Poikiloderma with Neutropenia (CPN) due to mutations in the C16orf57 gene. Mutations in the RECQL4 gene are only observed in two thirds of RTS patients. In this study, 10 patients referred for syndromic poikiloderma and negative for RECQL4 sequencing analysis were investigated for C16orf57 mutations. Two C16orf57 heterozygous nonsense mutations (p.W81X and p.Y89X) were identified in a 5-year-old female child presenting with generalized poikiloderma, dental dysplasia, gingivitis, nail dystrophy, palmoplantar keratoderma and pachyonychia of the great toenails. Previously undetected and silent neutropenia was evidenced after C16orf57 molecular analysis. Neutropenia was absent in the C16orf57-negative patients. This report confirms that neutrophil count should be performed in all patients with poikiloderma to target the C16orf57 gene sequencing analysis, prior to RECQL4 analysis. [Copyright &y& Elsevier]

Kindler syndrome (OMIM 173650) is an autosomal recessive condition characterized by skin blistering, skin atrophy, photosensitivity, colonic inflammation and mucosal stenosis. Fewer than 100 cases have been described in the literature. First reported in 1954, the molecular basis of Kindler syndrome was elucidated in 2003 with the discovery of FERMT1 (KIND1) loss-of-function mutations in affected individuals. The FERMT1 gene encodes kindlin-1 (also known as fermitin family homologue 1), a 77 kDa protein that localizes at focal adhesions, where it plays an important role in integrin signalling. In the current study, we describe five novel and three recurrent loss-of-function FERMT1 mutations in eight individuals with Kindler syndrome, and provide an overview of genotype-phenotype correlation in this disorder.

Background: Juvenile dermatomyositis is potentially life threatening rare autoimmune illness that mainly affects muscle and skin. Cutaneous features are useful in establishing the diagnosis of this disease. Case Summary: We report an 8-year-old male juvenile dermatomyositis who presented epidermal nevus like-lesions on the back of the right thigh. Characteristic cutaneous changes such as Gottron's papules of the hand, heliotrope rash of the eyelids, and poikiloderma-like lesions on the back were observed. Diagnosis of juvenile dermatomyositis was made by positive muscle biopsy and magnetic resonance imaging findings and typical cutaneous manifestations. However, epidermal nevus-like skin lesions, an acquired inflammatory dermatosis that follows Blaschko lines, seen in this case have been rarely reported in the literatures. Discussion: We would like to report this case and discuss about the significance and pathogenesis of this rare cutaneous manifestation like Blaschkitis in juvenile dermatomyositis.

A large number of other cutaneous and extracutaneous features have also been described.

A new syndrome with poikiloderma was described by Clericuzio et al. in 1991. 1 They reported 14 Navajo native Americans, including eight siblings, developing in the first year of life an erythematous rash, which started on the limbs and spread over the trunk and the face. This rash evolved into poikiloderma. All patients had recurrent bacterial infections. First published as Navajo poikiloderma this syndrome is now known as poikiloderma with neutropenia (PN, OMIM 604173). The inheritance is autosomal recessive, and mutations in a new gene, C16orf57, were recently described in two kindreds. 2 Because of the phenotypic overlap between Rothmund-Thomson syndrome (RTS) and PN, a few patients have been reclassified as mutations in the RECQL4 gene for RTS were absent. 2-5 Until now 27 patients have been described with clinical PN. 1-3,5-8 Here, we report the sixth family with PN outside the Navajo population. We found the previously unreported mutation c.243G>A, p.W81X in the C16orf57 gene, thus confirming the relation of this gene to the disease. 2,6 Because the molecular genetic diagnosis is not always available, we propose clinical and laboratory diagnostic criteria for PN.

Background Fewer than 5% of cases of mycosis fungoides (MF) present with a cytotoxic/suppressor CD8+ phenotype which, despite immunophenotypic similarities with CD8+ aggressive lymphomas, is regarded as a phenotypic variant of MF. Poikilodermatous MF showing a CD8+ phenotype has been reported to have a nonaggressive clinical behaviour and a good response to psoralen plus ultraviolet A treatment. Objectives To perform a retrospective study of CD8+ MF cases diagnosed in the skin lymphoma clinic of Andreas Sygros Hospital. Methods We analysed the clinical characteristics, the immunophenotypic and molecular indices, as well as the clinical course of these patients. Results Seven cases of CD8+ MF (6·5% of all cases of cutaneous T-cell lymphoma) were diagnosed during 2002–2007. One of seven patients had stage IA, five stage IB and one stage IIB disease. Clinical characteristics were variable: four of seven patients presented with poikilodermatous plaques (in one of them lesions of lymphomatoid papulosis with CD8+ phenotype coexisted), one patient with classic MF, one with plantar MF and one with follicular MF. The time period between disease onset and diagnosis was long for most patients (up to 33 years). All patients received the recommended treatment according to TNM staging. Five of seven patients had complete remission, one partial response and one stable disease. Conclusions Special clinical characteristics, such as hyperpigmentation and poikiloderma, are often noted in CD8+ MF cases. In our series CD8+ MF presented with a long-standing disease and indolent course suggesting that CD8+ cytotoxic immunophenotype may represent a marker of mild biological behaviour.

Kindler syndrome (OMIM 173650) is an autosomal recessive genodermatosis characterized by trauma-induced blistering, poikiloderma, skin atrophy, mucosal inflammation and varying degrees of photosensitivity. Although Kindler syndrome is classified as a subtype of epidermolysis bullosa, it has distinct clinicopathological and molecular abnormalities. The molecular pathology of Kindler syndrome involves loss-of-function mutations in a newly recognized actin cytoskeleton-associated protein, now known as fermitin family homologue 1, encoded by the gene FERMT1. This protein mediates anchorage between the actin cytoskeleton and the extracellular matrix via focal adhesions, and thus the structural pathology differs from other forms of epidermolysis bullosa in which there is a disruption of the keratin intermediate filament–hemidesmosome network and the extracellular matrix. In the skin, fermitin family homologue 1 is mainly expressed in basal keratinocytes and binds to the cytoplasmic tails of β1 and β3 integrins as well as to fermitin family homologue 2 and filamin-binding LIM protein 1. It also plays a crucial role in keratinocyte migration, proliferation and adhesion. In this report, we review the clinical, cellular and molecular pathology of Kindler syndrome and discuss the role of fermitin family homologue 1 in keratinocyte biology. [ABSTRACT FROM AUTHOR]

Members of two generations of a South African family have a unique syndrome comprising poikiloderma, tendon contractures and progressive pulmonary fibrosis. The condition is clinically important as the skin changes, which involve the face, have considerable cosmetic impact, while lung involvement is potentially lethal in adulthood. Skin manifestations which facilitate diagnosis include facial telangiectasia, mottled hypo- and hyperpigmentation, papules and epidermal atrophy. The scalp, facial and body hair are fine and scanty. The tendon contractures lead to progressive digital flexion deformities and abnormalities of the ankles and feet, with disturbance of gait. Pulmonary involvement manifests as progressive dyspnoea. Pedigree data are compatible with an autosomal dominant mode of transmission. Poikiloderma of Weary is characterized by linear sclerotic and fibrous bands and not tendon contractures and is not associated with potentially lethal pulmonary fibrosis. Rather than name this disorder a variant of Weary syndrome, it might be prudent to use as an umbrella title one composed by Weary himself: ‘hereditary sclerosing poikiloderma’ (HSP), under which variants such as HSP Weary type, HSP with cardiac involvement (aortic stenosis described as inconsistently associated with Weary syndrome) and HSP with tendon/pulmonary involvement (current family) may be classified. The manifestations in this family differ from other poikilodermata and, to the best of our knowledge, have not been previously documented. [ABSTRACT FROM AUTHOR]

Although a common dermatosis, idiopathic poikiloderma of the face and neck has not been studied in depth for decades. To reassess the clinical and epidemiological characteristics of poikiloderma of Civatte (PC). Fifty consecutive patients with PC. Evaluation included history taking and physical examination. Epidemiological and clinical parameters were recorded and analysed. The literature from 1923 until today, was reviewed thoroughly. The frequency of PC among dermatologic patients was estimated to be 1.4%. There were 34 females (68%) and 16 males in the present study. The mean age at diagnosis was 47.8 years for females and 61.7 years for males. The majority (88%) had skin phototype II or III. Among females, 26 were at their peri-menopausal stage, including three cases of iatrogenic menopause. Four patients reported that other blood-related family members also had PC. The v and the sides of the neck and the upper chest were most often affected in a symmetric distribution. The face (preauricular and parotid region) was involved in 19 patients (38%). The erythemato-telangiectatic clinical type predominated (58%), followed by the mixed (22%) and the pigmented type (20%). Almost half of the patients (46%) were symptomatic (itching, burning and ‘flushing’). The mean duration from onset to diagnosis was 6.2 years according to the patients’ report. The course was usually slowly progressive (82%) and irreversible. PC shows characteristic features, supporting the theory that it represents a distinct entity. It is rather common in Greece. Although menopausal women predominated in our cohort, men were not uncommonly affected and were diagnosed at an older age. Based on the predominating clinical feature, PC can be classified into three clinical forms. Symmetry and sparing of the anatomically shaded areas of the neck are highly characteristic for PC. Face involvement was not as common and as severe as it had been considered in the past. Recognition of clinical type is important for the selection of the most appropriate treatment, which, despite the advent of novel modalities, remains problematic. [ABSTRACT FROM AUTHOR]

Rothmund–Thomson syndrome (RTS) is a rare autosomal recessive disorder that is characterized by skin manifestations, juvenile cataracts, and extracutaneous manifestations. The presence of congenital airway abnormalities has not previously been documented in Rothmund–Thomson syndrome. We report the case of a child with Rothmund–Thomson syndrome suffering from multiple airway abnormalities. Our case highlights the importance of suspecting multiple airway abnormalities in any child with respiratory distress with other systemic anomalies. This necessitates meticulous anatomical and dynamic examination of the laryngotracheo-broncheal tree. [Copyright &y& Elsevier]

Summary Background Poikiloderma of the face and neck (Civatte) is a rather common, indolent, chronic dermatosis, most often affecting menopausal females. Cumulative excessive sun exposure, a phototoxic or a photoallergic reaction, hormonal changes of menopause and genetic factors have all been incriminated in its obscure aetiopathogenesis. Objectives To evaluate the role of contact sensitization and photosensitivity in the pathogenesis of poikiloderma of Civatte (PC). Methods Thirty-two patients (24 females and eight males, age range 38–74 years) with PC were patch tested with the European standard series and the fragrance series, and were photopatch tested with the photoallergens series. Additionally, photo-testing with a monochromator was performed. Results Thirteen of 32 patients (40·62%) had one or more positive reactions to allergens of the standard series. Eight patients (25%) had positive reactions to fragrance mix and/or Balsam of Peru, which are included in the standard series, or to allergens of the fragrance series. Nickel sulphate was the single most common cause of contact sensitization (18·75%) among our patients. Ninety-seven subjects, who were patch tested with the standard series for suspected allergic contact dermatitis of the face and/or neck, served as age, sex and site controls. Of these, nine (9·27%) had one or more positive reactions to fragrance compounds. Statistical analysis showed a statistically significant difference in the frequency of positive reactions to fragrances between the PC group and the control group (χ2 value = 3·91, P < 0·05). In contrast, none of the PC patients had a positive photopatch test for the allergens included in the photoallergens series. The estimated minimal erythemal dose for the PC group was in all cases within normal limits for all wavelengths of ultraviolet (UV) radiation examined. Conclusions Contact sensitization, mostly to perfume ingredients, may... [ABSTRACT FROM AUTHOR]

Kindler syndrome (KS) is a very rare genodermatosis characterized by acral blistering starting in infancy along with photosensitivity, progressive poikiloderma, cutaneous atrophy, and a variable degree of mucosal involvement. A large number of other cutaneous and extracutaneous features have been described, which aid in diagnosing it. Generally KS has been found to be associated with hypohidrosis/anhidrosis. We herein present a rare case of KS with unique features. [ABSTRACT FROM AUTHOR]

A three month-old boy was brought by his mother with complaints of multiple reddish lesions on his trunk and face since birth. The patient had erythematous annular plaques with scaling on his extremities, palms and soles with periorbital erythema and edema giving the characteristic "eye mask" or "owl's eye" appearance. His mother did not have history of any illness. Hemogram, liver and renal function tests were within normal limits. A skin biopsy was suggestive of subacute cutaneous lupus erythematosus. Immunological work-up was positive for antinuclear antibodies (ANA) (1:40) with anti-Ro titers of 3.4 and 3.47 (>1.1 = clinically significant titre) in the mother and child respectively, although negative for anti-La antibodies. The child's electrocardiogram and 2D echocardiography were normal. We are presenting a case of anti-Ro-positive cutaneous lupus erythematosus with an uncommon skin manifestation.

Kindler syndrome is a rare autosomal recessive disorder associated with skin fragility. It is characterized by blistering in infancy, photosensitivity and progressive poikiloderma. The syndrome involves the skin and mucous membrane with radiological changes. The genetic defect has been identified on the short arm of chromosome 20. This report describes an 18-year-old patient with classical features like blistering and photosensitivity in childhood and the subsequent development of poikiloderma. The differential diagnosis of Kindler syndrome includes diseases like Bloom syndrome, Cockayne syndrome, dyskeratosis congenita, epidermolysis bullosa, Rothmund-Thomson syndrome and xeroderma pigmentosum. Our patient had classical cutaneous features of Kindler syndrome with phimosis as a complication. [ABSTRACT FROM AUTHOR]

Background: Dermatomyositis is a humoral-mediated inflammatory myopathy with symmetrical proximal muscle weakness and dermatological manifestations such as Gottron's papules, heliotrope rash, periungual abnormalities, and flagellate erythema. Erythroderma is a severe and potentially life-threatening dermatological condition with diffuse erythema and scaling involving more than 90% of the skin surface area. Poikiloderma vasculare atrophicans refers to mottled hyperpigmentation and hypopigmentation of the skin with in-between telangiectases and areas of atrophy and is considered a variant of mycosis fungoides. Poikilodermatomyositis is the term given to the condition with poikiloderma and inflammatory myopathy. Only a few cases are reported on erythroderma in dermatomyositis and poikilodermatomyositis. Erythrodermal pattern of dermatomyositis transforming into poikilodermatomyositis is a recognized rare manifestation of dermatomyositis and we could find only one case report in the literature.Case Presentation: A 53-year-old Sri Lankan woman presented with intermittent fever of 5 months' duration with erythroderma. Later she developed progressive, symmetrical proximal muscle weakness. Following a short course of small dose steroids, erythroderma settled but changed to extensive poikiloderma involving more than 90% of her skin with her face being relatively spared. She had an early heliotrope rash, shawl sign, and Gottron papules. Electromyography and muscle biopsy were supportive of inflammatory myositis and skin biopsy showed evidence of dermatomyositis. Inflammatory markers and muscle enzymes were also elevated. Autoimmune antibodies and myositis-specific autoantibodies were negative. She was started on orally administered prednisolone 1 mg/kg per day with methotrexate 10 mg once a week and had a good response to treatment with resolution of the skin condition and improvement of muscle power. Imaging studies, endoscopies, and tumor markers did not reveal any malignancy.Conclusions: This case illustrates a rare presentation of dermatomyositis initially presenting as fever, erythroderma, and proximal muscle weakness and later developing poikiloderma involving more than 90% of the skin. It is important to be aware of this rare presentation to avoid misdiagnosis. With the currently available literature it is not possible to conclude that erythroderma is a bad prognostic factor in dermatomyositis or a predictive factor for a malignancy. Patients have a good response to steroids with a combination of immunosuppressants. [ABSTRACT FROM AUTHOR]
