Miliarial gout is a rare clinical variant of chronic tophaceous gout characterised by tiny milia-like papules containing chalky tophaceous material. In this report, we present a case of miliarial gout in a patient with known history of gouty arthritis and review the reported cases of miliarial gout in the literature to discuss its characteristics, diagnosis and treatment., (© 2021 The Australasian College of Dermatologists.)

Gradations in skin color are a consequence of differing amounts of melanin and their varying distribution. Although many darkly pigmented skin lesions are melanocytic and can be attributed to melanin content, the color of a black lesion can also be due to blood, necrotic tissue, or exogenous pigment. The source, pattern, and distribution of the color in black lesions usually offer important insight into its etiology. This contribution reviews conditions that can take on a black color, discussing the cause of the hue and any additional impact sun exposure may have., (Copyright © 2019 Elsevier Inc.

A 31-year-old woman was seen at our clinic with itching papules of the back after hijama treatments. Hijama treatments consist of superficially cutting the skin followed by cupping and are applied for a diversity of complaints, including pain. Our patient initially presented with sensitive and burning sensations at the cutting sites, but recently, the cutting sites started to itch as well. At physical examination, we saw perfectly aligned papules with a sign of Wickham's striae on her back where the skin had been cut. Further examination revealed comparable, solitary papules on the inside of her wrist, flank and chest. A skin biopsy confirmed the diagnosis lichen planus. The patient was prescribed betamethasone cream and we advised against further hijama treatments.

Introduction: Prurigo is one of the most common dermatological conditions during HIV infection and AIDS. It appears as an immunosuppression marker associated with HIV infection. The study objective was to determine the prevalence of prurigo in people living with the human immunodeficiency virus (PLHIV) in Fousseyni N'Daou Hospital of Kayes, and to describe the socio-demographic aspects of patients and lesions associated with prurigo among PLHIV., Methods: It was a descriptive cross-sectional study included all cases of HIV infected patients with prurigo in the Dermatology-Venomology Department of Fousseyni N'DAOU Hospital from January 1, 2015 to August 31, 2015., Results: We collected 121 cases of prurigo. The hospital prevalence was 14.5% among PLHIV with 65% Female and the average age was 34.8 years old (SD: 15-81 years). The elementary lesions associated with prurigo were seropapules (40.2%), vesiculo-crusts (13%), excoriated papules (33.3%), lichenified papules (10.8%), and cicatricial lesions (2.7%). The prurigo was generalized in 68.5% of cases and localized in 31.24%. More than half of our patients had weight loss, fever, diarrhea and oral candidiasis in their medical history. Patients were infected with HIV1 in 60.03% and HIV1+ 2 in 24.3%. More than the half of our patients had a CD4 count inferior to 250 cells/mm3 at the time of prurigo diagnosis., Conclusion: In our study, prurigo remains a common condition in PLHIV, particularly in patients with low CD4 counts. Early detection and rapid antietroviral therapy can reduce the frequency of prurigo in PLHIV., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

Dermatosis papulosa nigra was first described by Aldo Castellani (1874-1971) more than 90 years ago, and it has since been presumed to be a variant of seborrheic keratosis. Despite their morphologic similarities both macroscopically and microscopically, key differences have yet to be explained. These lesions also exhibit different demographics, with dermatosis papulosa nigra having a predilection for dark-skinned individuals and a female predominance. No studies to date have investigated this, but studies assessing the mechanisms of similar dermatologic conditions may yield significant clues. The additional impact of environmental factors may also be important, but much controversy exists. Further investigations into dermatosis papulosa nigra are necessary to determine its pathogenesis and whether it should be regarded as a distinct entity., (Copyright © 2017 Elsevier Inc.

This patient was initially told he had genital warts, but the appearance of the lesions, and the presence of a rash on his trunk and extremities, suggested another diagnosis.

Background: Anaplastic large cell lymphoma is rarely diagnosed during pregnancy, and patients may be erroneously diagnosed with a dermatosis., Case: A 34-year-old female was diagnosed with pruritic urticarial papules and plaques of pregnancy in the third trimester. She underwent elective repeat cesarean section with a postoperative course complicated by skin and gingival ulcers and persistent fever. Imaging revealed lung and brain nodules. Video-assisted thoracic surgery lung biopsy demonstrated anaplastic large cell lymphoma., Conclusion: It is important to consider the diagnosis of anaplastic large cell lymphoma in a pregnant patient who presents with cutaneous symptoms.

Background: Cutaneous graft-versus-host disease (GVHD) is classically described as morbilliform when acute and lichen planus-like or sclerotic when chronic. In addition to these well-known clinical forms, there are many other presentations of GVHD that are important to recognize. As the number of patients undergoing stem cell transplantation increases and the survival after transplantation improves, the prevalence of GVHD is expected to rise, and its various presentations will be increasingly encountered in clinical practice., Objective: We sought to report unusual manifestations of skin GVHD and provide a summary of typical and atypical presentations of GVHD reported in the literature., Methods: Patients with stem cell transplantation who developed unusual eruptions after transplantation had biopsy specimens taken to evaluate for histopathologic evidence of GVHD., Results: Six patients presented with unusual cases of biopsy-proven GVHD, including follicular hyperkeratosis, thick-appearing white tongue, inverse pityriasis rosea-like, and eczema craquelé-like GVHD., Limitations: This study is limited by case number., Conclusions: Because of the high rate of cutaneous involvement with GVHD, the accessibility of the skin for diagnosis, and the morbidity associated with severe or long-standing skin involvement, it is important for dermatologists to recognize and accurately diagnose cutaneous GVHD in all its protean manifestations., (Copyright © 2014 American Academy of Dermatology, Inc.

We report a rare case of multicentric reticulohistiocytosis (MRH) associated with liver carcinoma. A 36-year-old man who had been diagnosed as having liver carcinoma for 2 years presented with a 2-month history of multiple papulonodules on the face, ears, neck, and upper chest, accompanied by progressive polyarthralgia of the hands, wrists, elbows and knee joints without fever or chills. Skin histology revealed well defined dermal infiltrate consisting of multinucleated giant cells and macrophages having abundant eosinophilic finely granular cytoplasm with ground glass appearance. Further immunohistochemical studies characterized the lesions as positive for CD68, CD45 and Vimentin. A diagnosis of MRH that was associated with liver cancer was made. Treatment with prednisolone for 2 months resulted in a significant improvement of the skin and joint symptoms, but was discontinued due to his significant enlargement and extensive metastases of the liver carcinoma.

Idiopathic immune myopathies (IIM) are an heterogeneous group of autoimmune muscle disorders characterized by progressive muscle involvement. Dermatomyositis (DM) is the most common form of IIM. It is a multisystem disorder characterized by symmetric proximal, extensor, inflammatory myopathy, vascular involvement and a characteristic cutaneous eruption. Six types of DM have been identified: idiopathic, juvenile (JDM), cancer-related other autoimmune diseases-related, iatrogenic DM and amyopathic DM. Cutaneous manifestations of DM are the most important aspect of this disease and can precede from several months to years muscle or systemic involvement. Three groups of signs have been described: pathognomonic, highly characteristic and compatible. Although differences exist among the different clinical presentation of skin lesions, they share common histological findings including the presence of interface dermatitis with epidermal atrophy, basement membrane degeneration, vacuolar alteration of basal keratinocytes, and dermal changes consisting of interstitial mucin deposition and a sparse lymphocytic infiltrate. DM is a serious disease; the correct evaluation of any skin lesion suggesting an early diagnosis is of utmost importance. Skin signs may, also, represent a marker of treatment efficacy even though systemic symptoms worsening may not always be followed by more severe skin lesions.

Tattoo is a popular cosmetic decoration, however several different tattoo-induced complication have been described. Several tattoo related cutaneous reactions such as allergic, granulomatous, lichenoid reactions, and infections have been reported. A 20 year-old male presented with multiple papules on the dragon shaped tattoo. The clinical and histopathological assessments were consistent with verrucas. Tattoo has become increasingly popular among young people. People interested in tattoos should be informed on its related infections and complications during and following tattooing. Herein, we present this rare tattoo induced verru plane to point out tattoo related complications and its treatments.

Introduction: Papulopruritic eruption (PPE) occurs in people living with HIV in India. Understanding the risk factors associated with this disease may help decrease the prevalence of PPE., Methods: This study was a case-control study performed at the Government Hospital of Thoracic Medicine, a tertiary care hospital in Chennai, India. Cases included HIV-positive, antiretroviral (ARV) therapy-naïve adults experiencing a pruritic skin eruption for longer than one month, with evidence of multiple papular or nodular lesions and biopsy consistent with arthropod bite. Controls included HIV-positive, ARV-naïve patients without active skin rash. Main outcome measures were CD4 cell count, histology, and environmental exposures. We performed statistical analysis using Epi Info version 3.5.1 and SPSS version 11.0 (SPSS Inc., Chicago, IL). Categorical variables such as gender, urban versus rural residence, occupation, treatment history, CD4 count, use of insect repellents, and environmental exposures were evaluated using the χ(2) test (or the Fisher exact test when an expected value for a category was less than 5). The t-test was used to evaluate differences in age and the duration since HIV diagnosis. The Mann-Whitney test was used to compare non-normally distributed values such as CD4 cell count. A p-value that was less than 0.05 was considered to be statistically significant., Results: Forty-one cases and 149 control subjects were included. Subjects with PPE had significantly lower CD4 cell counts compared to controls (225.5 cells/µL vs. 425 cells/µL; p=0.0001). Sixty-six percent of cases had a CD4 cell count less than 350 cells/µL. PPE cases were less likely to use mosquito repellent techniques (odds ratio 2.81, CI = 1.45-5.45)., Discussion: PPE may be an altered and exaggerated immune response to arthropod bites in HIV-positive patients. CD4 cell count is significantly lower in patients with PPE, and therefore it may be considered a qualifying clinical finding for ARV initiation in resource-poor settings. Protective measures against mosquito bites appeared to be important in preventing PPE in subjects at risk.

Background: Weathering nodules of the ear are pale yellow, asymptomatic lesions which predominate on the helices of the ears. Although their pathogenesis remains unknown, there is an association with chronic exposure to ultraviolet radiation, age and thermal injuries. Few studies have been conducted to date, and these involved a very small number of patients., Objective: Study the prevalence of weathering nodules of the ear in patients treated in the Dermatology Service of the State Civil Servant's Hospital of São Paulo, and evaluate their probable relationship with sun exposure, age and phototypes I and II., Methods: Four hundred patients older than 20 years of age were examined between July 2008 and December 2008. A questionnaire evaluating age, sex, place of birth, origin, occupation and history of sun exposure was applied. All patients were examined and evaluated for the presence of lesions by only one person., Results: The data showed that 155 (38.8%) patients had a lesion in at least one of the ears. The Chi-Square Test was used for the comparative analysis between the groups of patients with and without lesions. In the group of patients with lesions, 29% were 70 to 79 years old, 78.1% had a history of sun exposure and 45.1% belonged to FITZPATRICK skin phototypes I and II (p<0.05%)., Conclusion: The findings suggest relevant prevalence, probable association with chronic sun exposure, advanced age and phototypes I and II.

Favre-Racouchot disease commonly presents as comedones, cysts and elastosis in the periocular region of older men. Its etiology has been linked to several exogenous factors. Here we present 2 patients with strictly unilateral manifestation of the disease and a corresponding history of predominantly one-sided chronic occupational sun exposure and smoking, making the case for the causative role of these two factors., (Copyright © 2013 S.

Objective: Persistent pruritic eruptions (PPE) are common among our patients with adult-onset Still disease (AOSD). We aimed to characterize the clinicopathologic features of the AOSD-associated evanescent and persistent rashes., Methods: We reviewed the clinicopathologic features of the skin lesions from all AOSD cases diagnosed in our hospital during 1988 to 2009. The diagnoses were based on Yamaguchi criteria for AOSD., Results: Altogether, there were 36 patients (6 men and 30 women) with age of onset ranging from 17 to 67 years (average 35.7 years). Evanescent rash was recorded in 31 patients (86%) and PPEs in 28 (78%). PPEs usually appeared at the disease onset and manifested as widespread, pruritic, erythematous urticarial or violaceous to brownish flat-topped (lichenoid) papules and plaques over the trunk, neck, face, and extensor sides of the extremities. PPEs were classified clinically as urticarial papules (n = 21), lichenoid papules (n = 18), prominent linear and dermographism-like (n = 11), dermatomyositis-like (n = 7), prurigo pigmentosa-like (n = 4), and lichen amyloidosis-like (n = 2). The clinical activity score was 5.78 ± 1.11 (range 4 to 8) for the series and 6.57 ± 0.98 and 5.57 ± 1.07, respectively, for the groups with and without dermatomyositis-like PPE (P = 0.0314). Five patients died, 3 of them with dermatomyositis-like PPE. Histopathologically, the evanescent rash (8 specimens) showed a superficial perivascular infiltrate of lymphocytes and neutrophils, whereas the PPEs (32 specimens) revealed solitary or cluster necrotic keratinocytes in the superficial epidermis with infiltration of lymphocytes and neutrophils in the upper and mid dermis., Conclusions: PPEs were very common among our patients with AOSD. Recognition of the characteristic clinical and pathologic features of PPE can facilitate diagnosis of AOSD. Therefore, biopsy of atypical eruptions in AOSD patients is recommended because it is likely that the highly distinctive histopathologic features will allow these eruptions to be readily classified., (Copyright © 2012 Elsevier Inc.

Background: Antiphospholipid syndrome (APS) is characterised by arterial or venous thrombosis combined with the presence of specific antibodies known as antiphospholipids. It is commonly associated with cutaneous signs. Herein we report a case of atypical cutaneous eruption occurring during the course of APS and we discuss the possible mechanism., Patients and Methods: A 45-year-old woman consulted twice within six months for an erythematosus papular eruption around the neckline. She was being followed-up for antiphospholipid syndrome treated with fluindione (Préviscan®), and her International Normalized Ratio (INR) was consistent with the prescribed anticoagulation target. Blood tests confirmed the presence of anticardiolipin and antiphospholipid antibodies, but no laboratory evidence of lupus was seen. Histopathological examination of a skin biopsy demonstrated the presence within the vascular lumen of a weakly eosinophilic anhistic substance positive for PAS stain. The patient was given acetone salicylic acid (Kardégic®) combined with fluindione, and four years later, she had presented no relapses., Discussion: Despite a clinically evocative appearance, the diagnosis of lupus tumidus was ruled out in our patient by histopathological features, and associated systemic lupus erythematosus was repeatedly refuted on the basis of clinical and laboratory data. We suggest that the specific histological images of intraluminal deposits within the dermal vessels seen in this patient, although not typical of thrombosis, are associated with APS. The clinical remission seen from the start of antiplatelet treatment could be due to the action of these drugs against the obstruction of small-calibre dermal vessels., (Copyright © 2012 Elsevier Masson SAS.

Reiter disease (RD) is characterized by a triad of sterile arthritis, urethritis and conjunctivitis. The conditions occur concomitantly or sequentially, and are associated with mucocutaneous features such as circinate balanitis and stomatitis. Arthritis usually occurs in attacks followed by recovery, but it sometimes progresses to permanent damage of the affected joints. Because the symptoms of this disorder are attributable to activated neutrophils, we assessed the efficacy of granulocyte and monocyte adsorption apheresis (GCAP) in a 73-year-old man with RD who had skin rashes on his penis, scrotum and right hand, with severe arthralgia. The patient's skin rash and joint pain responded dramatically to five sessions of GCAP delivered at intervals of 5 days. We present a detailed description of the patient and discuss the mechanisms of GCAP, and suggest that GCAP may be useful for treating RD., (© The Author(s).
