The aim of this study was to determine the efficiency of a keloid treatment consisting of intradermal surgical shave excision followed by intralesional injections of Bleomycin. A retrospective study performed in the Department of Dermatology, CHU UCL Namur Sainte Elisabeth Clinic, Belgium between 2018 and 2019, on 314 patients with keloids-average age: 32 years (range 19-62). Patients were treated first by surgical shave excision and then after reepithelialization, monthly Bleomycin injections were used until the itching and/or pain ceased and the keloid disappeared. The satisfaction index based on Vancouver Scar Scale on the 314 patients was as follows: 87% of the patients were very satisfied with complete flattening (276 patients), 11% were moderated satisfied with significant flattening (32 patients), and 2% show recurrences (6 patients). Pain and itching disappear totally (100% of patients) based on Visual Analogue Scale. The absence of recurrence within 24 months of the last injection, leads us to believe that this can be a first choice and low-cost treatment, whatever the phototype and the size of the lesion. This treatment can be given in all regions of the world, including in non-industrialized or developing countries.

Paediatric atopic dermatitis (AD) can be burdensome, affecting mental health and impairing quality of life for children and caregivers. Comprehensive guidelines exist for managing paediatric AD, but practical guidance on using systemic therapy is limited, particularly for new therapies including biologics and Janus kinase (JAK) inhibitors, recently approved for various ages in this indication. This expert consensus aimed to provide practical recommendations within this advancing field to enhance clinical decision-making on the use of these and other systemics for children and adolescents aged ≥2 years with moderate-to-severe AD. Nineteen physicians from Northern Europe were selected for their expertise in managing childhood AD. Using a two-round Delphi process, they reached full or partial consensus on 37 statements. Systemic therapy is recommended for children aged ≥2 years with a clear clinical diagnosis of severe AD and persistent disease uncontrolled after optimizing non-systemic therapy. Systemic therapy should achieve long-term disease control and reduce short-term interventions. Recommended are cyclosporine A for short-term use (all ages) and dupilumab or methotrexate for long-term use (ages ≥6 years). Consensus was not reached on the best long-term systemics for children aged 2-6 years, although new systemic therapies will likely become favourable: New biologics and JAK inhibitors will soon be approved for this age group, and more trial and real-world data will become available. This article makes practical recommendations on the use of systemic AD treatments for children and adolescents, to supplement international and regional guidelines. It considers the systemic medication that was available for children and adolescents with moderate-to-severe AD at the time this consensus project was done: azathioprine, cyclosporine A, dupilumab, methotrexate, mycophenolate mofetil and oral glucocorticosteroids. We focus on the geographically similar Northern European c

Urticaria multiforme, first described in 1997, also called acute ring urticaria, is a clinical variant of acute urticaria. We relate the case of a 16-year-old adolescent with an extensive pruritic eruption of erythematous annular lesions of variable shapes, arciform, or polycyclic with an ecchymotic center. Urticaria multiforme is described in children aged from 4 months to 4 years, rarely in adolescents. As far as we know, this is the 4th case reported in the literature.

A 66-year-old white female presented with a generalized, erythematous, and itchy eruption for 3 days after. She reported having fever on the first day of eruption, complaints of asthenia, and anorexia with no other systemic symptoms. She received her first dose of Vaxzevria (AstraZeneca, Cambridge, UK) against COVID-19 three weeks prior. The eruption started on the right arm at the vaccine injection site and then spread progressively throughout the entire body. We noticed multiform erythema- like patches with three or four concentric circles with different shades of redness. Anatomopathological analysis indicated a lichenoid histological pattern compatible with adverse event of vaccine. Degressive general corticotherapy was prescribed with an improvement of the symptomatology and complete healing in ten days. Physicians should be aware if this rare adverse event. Drug-induced lichenoid exanthema is considered a non-severe reaction and does not contraindicate the readministration of essential drugs. In this case, the patient refused the second injection of Vaxzevria.

Fish pedicures and/or fish manicures are treatments performed in spas involving the use of the living fish . In the last decade, the use of for cosmetic and therapeutic reasons has become increasingly popular. The patients are placed into a bath to control psoriasis, eczema, or other skin conditions, but there is no scientific proof of their effectiveness. Most of the infections described in association with fish spas result from minor skin injury and contact with fish carrying such bacteria as , and Therefore, fish spas in general should not be recommended, particularly for diabetic patients, immunocompromised patients, or patients treated with biological agents.

Halo nevi are often considered benign, and the possibility of malignancy is not always clear to practitioners. We present two case reports suggesting that a halo nevus appearance can be seen in melanoma, even in young adults. A literature search for halo nevi revealing melanoma shows that this is a very rare condition. . This report of two young patients indicates the importance of obtaining a detailed history to detect warning signs such as itching, pain, spontaneous bleeding, and previous alterations according to the patient, including a previously totally black colour in an already fully regressed melanoma. The risk of a halo nevus being malignant is higher if there is only one unique halo nevus and no personal or familial history of vitiligo. We postulate that a regressing atypical nevus or a regressing melanoma may be induced by an immunologic reaction as halo nevus type of clinical picture.

When the diagnosis of penile calciphylaxis is suggested, the evolution of the disease is rapidly unfavorable; in this case, a rapid medical treatment must be established to obtain an improvement of the disease to avoid penectomy.

Anaplastic large cell lymphoma (BIA-ALCL) associated with rough textured breast implants was first reported in 1997. It is a non-Hodgkin's lymphoma originating from a T lymphocyte which occurs on average 10.9 years after placement of the breast implant. BIA-ALCL mainly manifests as a periprosthetic seroma or a mass adjacent to the implant. To our knowledge, we describe the first case of BIA-ALCL with initial presentation by indurate erythematous plates located in both breasts and the progressive appearance of several asymptomatic metastatic nodular lesions that have been appearing on the right arm some weeks later.

Herein, we follow the case of a patient suffering from papulopustular rosacea caused by Demodex associated with polycythemia vera (PV), which was fortuitously diagnosed. Facial erythrosis must spark a suspicion of PV even if the case appears to be papulopustular rosacea caused by Demodex. This observation underlines the distinctive physiopathological processes of papulopustular rosacea caused by Demodex and that of PV; however, the dermatological clinical signs are similar. A skin biopsy does not allow us to differentiate the two pathological processes since only a blood sample analysis may exclude a diagnosis of PV. This case stresses the potential advantage of conducting systematic blood analyses for every patient presenting with clinical signs of rosacea, even of erythrodermic rosacea that does not respond to the classical therapeutics, to exclude the possibility of underlying asymptomatic PV. Dermatologists must be aware of the nonspecific dermal manifestations of this potentially fatal hematologic disorder.

BACKGROUND: CD8+ CD30+ primary cutaneous T-cell lymphomas (PCTCL) are rare entities with overlapping pathological features and variable outcome. OBJECTIVES: We sought to highlight the importance of correlation between pathological findings and clinical presentation for correct classification of the disease. MATERIALS & METHODS: Two cases of CD8+ CD30+ PCTCL were investigated. The first patient presented with a multiple necro-erythematous lesion of the limb and the second with a papulo-necrotic lesion of the eyelid. RESULTS: Despite a different clinical presentation, pathological findings were similar in both cases. Clinico-pathological correlation led to a diagnosis of primary cutaneous CD8+ aggressive epidermotropic cytotoxic T-cell lymphoma in the first case and primary cutaneous anaplastic large-cell lymphoma in the second. The first patient died shortly after diagnosis and the second is alive without recurrence. CONCLUSIONS: Clinico-pathological correlation is essential for the correct identification of these rare diseases.

The incidence of seborrheic keratosis (SK) generally increases with age and are mostly localized on the trunk, face and neck, especially on sun-exposed areas. The association between SK and skin malignancies appears to be accidental, but transformation occurs more frequently in sun-exposed areas. Histopathological examination of all SK cases should be considered, especially when SK lesions exhibit atypical clinical manifestations, such as ulceration and cresting, as they may herald malignant transformation. In addition, other features associated with malignant transformation include excoriations or hemorrhages identified on the lesion, modification and evolution of the macroscopic characteristics, and the presence of local erythema or pruritus. Immunocompromised patients exhibit an increased risk of malignant transformation, even when radiation is involved.

Dermatomyositis pathophysiology is complex. In recent years, medical research has identified molecules associated with disease activity. Besides providing insights into the driving mechanisms of dermatomyositis, these findings could provide potential biomarkers. Activity markers can be used to monitor disease activity in clinical trials and may also be useful in daily practice. This article reviews molecules that could be used as biomarkers for diagnosis and monitoring dermatomyositis disease activity.

CD30+ cutaneous anaplastic large-cell lymphoma is part of the CD30+ T-cell lymphoproliferative disorders. This type of lymphoma is in most cases indolent, with a high survival rate. We report the case of a 59-year-old patient with a 1-month lasting crusty lesion of the upper eyelid. Eyelid involvement is very uncommon, as the most frequent locations are the trunk and the limbs.

Introduction. Paget's extramammary disease mostly affects genital, perianal and axillary regions. Whilst triple involvement has been described in Japanese patients, simultaneous lesions of both axillary regions and the inguinal area are exceptional among European patients. We report a case of triple Paget's extramammary disease in a Caucasian patient. Case-report. A 79-year-old male patient who developed a prostatic adenocarcinoma 3 years ago, was seen for an erythemato-squamous intertrigo of both axillary folds and the pubic area, present for 10 years, not diagnosed and resistant to topical treatments. Triple Paget's extramammary disease was confirmed by both histopathological and immunohistochemical investigations. No recurrence of the prostatic adenocarcinoma was observed. Discussion. Since the first description of triple Paget's extramammary disease, 28 cases have been reported in Japan. To our knowledge, this is the first case observed in a Caucasian patient. The clinical features of axillary lesions are described as pigmented or depigmented plaques, sometimes lichenoid or erosive. For some Japanese authors, a biopsy is mandatory even in the absence of clinical lesions, since typical Paget cells can be found. Immunohistochemical studies reveal CK7 expression, the marker of choice for primary extramammary Paget's disease. CK7 - would suggest underlying regional internal malignancy as well as CK20 +. Despite the fact that the immunophenotype was CK7 +/CK20- the patient developed an evolving prostatic adenocarcinoma. Although various treatments are described in the literature, surgical excision remains the first line treatment whenever possible.
