Abstract
BACKGROUND Dystrophic epidermolysis bullosa pruriginosa (DEB-Pr) is a rare subtype of hereditary epidermolysis bullosa, with a poorly understood pathogenesis and no satisfactory treatment. OBJECTIVES To assess the clinical and biological features, genetic basis and therapeutic management, to better characterize this rare genodermatosis. METHODS We have conducted a retrospective study, reviewing the clinical presentation, genetic diagnosis, immunohistopathological findings and biological characteristics and management of patients with dystrophic epidermolysis bullosa pruriginosa. This study was conducted in the Department of Dermatology at Saint-Louis Hospital and the Department of Genetics at Necker Hospital (Paris, France). All patients with a diagnosis of DEB-Pr seen between 2010 and 2020 were included. RESULTS Seven patients were included, the average age of 50.1 years [range 36-76]. Pruriginous-lichenified papules, plaques or nodules appeared at 27.6 years on average [range 7-66] on pretibial areas and forearms, associated with milia and toenails dystrophy. All patients received multiple treatments, but none could sustainably reduce pruritus. Immunohistopathological analysis of lesion skin revealed subepidermal blister with fibrosis, milia and mast cell infiltration. Serum TNFα, IL1β and IL6 levels were elevated in 2/6 patients. Total serum IgE levels were increased in 7/7 patients, with no history of atopy. Immunophenotyping of circulating T-cells revealed an increased Th2 subset in 4/4 patients, with reduced Th1 and Th17 subpopulations. Genetic analysis of COL7A1 identified 7 distinct causative mutations, six of which were new. Intra-familial clinical variability was documented in 5/7 patients and was associated with the co-inheritance of a recessive COL7A1 mutation or an FLG2 mutation in 2 families. CONCLUSION Our study confirms the stereotyped presentation of DEB-Pr with large intra-familial variability in disease expression. Mast cell infiltration, elevated IgE and increased Th2 subset without atopy strongly support a role of Th2-mediated immunity in DEB-Pr, and further argue for new targeted therapeutic options such as dupilumab.

Abstract
BACKGROUND Primary cutaneous lymphomas (PCLs) are a heterogeneous group of T-cell (CTCL) and B-cell (CBCL) malignancies. Little is known about their epidemiology at initial presentation in Europe and about potential changes over time. OBJECTIVES The aim of this retrospective study was to analyse the frequency of PCLs in the French Cutaneous Lymphoma Registry (GFELC) and to describe the demography of patients. METHODS Patients with a centrally validated diagnosis of primary PCL, diagnosed between 2005 and 2019, were included. RESULTS The calculated incidence was unprecedently high at 1·06 per 100 000 person-years. The number of included patients increased yearly. Most PCL subtypes were more frequent in male patients, diagnosed at a median age of 60 years. The relative frequency of rare CTCL remained stable, the proportion of classical mycosis fungoides (MF) decreased, and the frequency of its variants (e.g. folliculotropic MF) increased. Similar patterns were observed for CBCL; for example, the proportion of marginal-zone CBCL increased over time. CONCLUSIONS Changes in PCL frequencies may be explained by the emergence of new diagnostic criteria and better description of the entities in the most recent PCL classification. Moreover, we propose that an algorithm should be developed to confirm the diagnosis of PCL by central validation of the cases.

Abstract
Orf is a DNA parapoxvirus transmitted to humans by contact with infected goats and sheep. Many complications have been reported after orf infection, including erythema multiforme. A few cases of autoimmune bullous dermatosis complicating orf disease have been reported to date. They are usually characterized by tense blister eruptions with or without mucosal involvement; linear deposition of C3, IgG and/or IgA along the basement membrane; and negativity of indirect immunofluorescence analysis and enzyme-linked immunosorbent assay (ELISA) (performed in four of 11 reported cases). These analyses have targeted antigens of bullous pemphigoid, mucous membrane pemphigoid or epidermolysis bullosa acquisita, except one case of mucosal pemphigoid with antilaminin-332 antibodies. We describe the case of a patient who presented with an ulceration on his finger 10 days after direct contact with a lamb during Eid al-Adha. Four weeks later he developed a severe tense blistering eruption associated with mucous membrane erosions. Indirect immunofluorescence analysis using the patient's serum revealed circulating antibasement membrane IgG that bound the dermal side of salt-split skin. ELISA was positive for recombinant immunodominant NC1 domain of type VII collagen. We finally diagnosed epidermolysis bullosa acquisita complicating probable human orf infection.

Abstract
BACKGROUND Microcystic adnexal carcinoma (MAC), syringomatous carcinoma (SC) and "Squamoid eccrine ductal carcinoma" (SEDC) are rare sclerosing adnexal tumours. OBJECTIVE To understand the histogenesis of these tumours and possible clinical implications. METHODS We conducted a retrospective study of 30 cases, 18 MAC, 5 SC and 7 SEDC reviewed and classified by a panel of dermatopathology experts, with immunohistochemical analysis of keratins, including K77, a new keratin specific of eccrine ducts, and PHLDA1 expressed in adnexal structures. RESULTS There was a strong female predominance, with only five cases occurring in men. Patients with MAC and SC were younger (mean age 56 and 47 years) than those with SEDC (mean age 81 years). The most common localization was the cheek in SC and SEDC and the periocular area in MAC. Two cases of SEDC were found in organ transplant patients. No recurrence or metastases were observed after complete surgery of MAC, or SC (mean follow-up 7.2 years and 4.7 years), whereas one case of SEDC recurred and another could not be fully excised. MAC and SC had similar histological features, except for cysts. In MAC, calcifications, granulomas, connection to follicles, keratin expression pattern, PHLDA1 positivity and K77 negativity indicated a follicular histogenesis, whereas in SC, K77 positivity and keratin expression pattern were consistent with a differentiation towards eccrine apparatus. SEDC was composed of strands centred by ducts and nests with squamous differentiation and displayed K77 ductal positivity in all cases, a finding consistent with an eccrine origin. CONCLUSION Our study demonstrated that MAC and SC have similar clinical characteristics, although histogenesis differs and show arguments for the individualization of SEDC.

Abstract
Pyoderma gangrenosum (PG) is a non-infectious purulent ulcerative disease triggered mainly by chronic inflammatory bowel disease, monoclonal gammapathy, polyarthritis and haematological malignancies; exceptionally, it can be triggered by surgery alone. When PG is associated with fever, it can mimic infectious cellulitis. When it is located on the breast, unnecessary and deleterious surgical debridement may be performed. We present two cases of PG of the breast. The first is a postoperative PG and the second was associated with acute myeloid leukaemia - both led to unnecessary surgery. Several elements may have helped to make the diagnosis: nipples little affected by PG, symmetrical lesions on both breasts, other similar lesions elsewhere on the body, resistance to wide spectrum antibiotherapy, complete blood count abnormalities and negativity of bacterial culture. We propose an index to help the surgeon in his decision to realise a surgical debridement or to postpone it and consider the diagnosis of PG.

Abstract
BACKGROUND Systemic capillary leak syndrome (SCLS) is a severe disorder characterized by unexplained rapid transfer of considerable volumes of plasma from the intravascular to the extravascular compartment. For some cases of SCLS, no aetiology is evident and these cases are reported as idiopathic (ISCLS). OBJECTIVES To describe the cutaneous findings in 3 patients with ISCLS. RESULTS Cutaneous involvement consisted in sclerosis, livedo, purpura and photodistributed maculopapular erythematous rash. Dermal mucinosis was proven by biopsy in 1 patient. No underlying disease was diagnosed during follow-up. CONCLUSION The above-mentioned cutaneous findings can be present during acute attacks of ISCLS. They seem specifically related to the ISCLS and not indicative of an underlying disease.

Abstract
To the best of our knowledge, only 3 cases of cutaneous polyarteritis nodosa (PAN) treated successfully with methotrexate (MTX) have been reported in the medical literature. We report 2 further cases of steroid-dependent cutaneous PAN treated successfully with low-dose weekly MTX therapy. The clinical and biological tolerance of MTX was excellent. The cutaneous lesions started to regress within 3 weeks. One of the patients reported full recovery which lasted 2 years after stopping the therapy. So, MTX seems to be an interesting therapy in the treatment of PAN because of its relatively low toxicity, its simple use, its quick action and prolonged results after MTX has been stopped.

Abstract
Bullous ichthyosiform erythroderma (BIE) and non-bullous ichthyosiform erythroderma (NBIE) are rare congenital ichthyoses. Generalized pustular psoriasis (GPP) of von Zumbusch type is a rare and severe form of psoriasis marked by desquamative and pustular erythroderma associated with fever and altered general conditions. We report two adults with an ichthyosis typical of BIE in the first case and NBIE in the second, without any previous history of psoriasis, who presented with a severe and relapsing GPP of von Zumbusch type. Using current knowledge of the genetic relationship between psoriasis and congenital ichthyoses, we discuss the possibility of a common physiopathological link between congenital ichthyoses and GPP, and examine the possible therapeutic problems resulting from this pathological association, especially in BIE.

Abstract
Reactive angioendotheliomatosis (RAE) is a rare benign cutaneous vascular proliferation characterized by intravascular hyperplasia of endothelial cells and tuft-like proliferation of vessels. A 75-year-old man had erythematous and violaceous macules, some stellate and others arranged in a livedoid pattern, evolving toward necrosis with central areas having an "atrophie blanche" appearance spread on the trunk, inguinal folds, and right thigh. He was on hemodialysis and had a benign monoclonal gammopathy. Cutaneous biopsy revealed RAE characterized by the proliferation of epithelioid and spindle-shaped cells in superficial and middermis lining vascular channels, arranged in clusters, and sometimes displaying an intravascular growth pattern. These cells stained for CD31, CD34, and actin. Interestingly, prominent amyloid deposits were found in the wall of some vessels in deep dermis, often causing obstruction of their lumina. The cause of RAE is unknown, but it can be associated with infections, antiphospholipid syndrome, dysglobulinemia, cryoproteinemia, and lower extremities arteritis, and it may occur near arteriovenous fistulas. In this patient, we believe that RAE was caused by obliteration of dermal vessels by amyloid deposits. Indeed, it is thought that RAE could be caused by ischemia secondary to vascular obstruction. This is the first reported patient with RAE associated with amyloid deposits.

Abstract
The aim of this study was to analyse the association between human herpesvirus type 8 (HHV8) and sarcoidosis. Using nested polymerase chain reaction (PCR), we tested the presence of HHV8 DNA sequences in 13 skin specimens and peripheral blood mononuclear cells from eight patients suffering from sarcoidosis. We also looked for the presence of HHV8 antibodies in the sera of 28 patients with sarcoidosis using three techniques: two indirect immunofluorescence assays and an enzyme-linked immunosorbent assay with recombinant capsid protein fragment encoded by open-reading frame 65. HHV8 PCR analysis was negative while HHV8 serological studies showed an overall prevalence of 18% among patients suffering from sarcoidosis: 43% in patients from sub-Saharan Africa, 17% in patients from Northern Africa, 12.5% in patients from the French West Indies and 0% in French patients. In conclusion, our results do not indicate an association between HHV8 and sarcoidosis but reflect the seroepidemiology of this virus in different geographical regions.

Abstract
The epithelioid vascular tumors include epithelioid hemangioma, epithelioid hemangioendothelioma and epithelioid angiosarcoma. We report the case of a difficult to define vascular epithelioid tumor. The tumor localized in the head developed in an eruptive way in multiple bone and skin locations in a 22-year-old man. The lesions had the same histological features as those of epithelioid hemangioma and epithelioid hemangioendothelioma with a spindle-cell component. This tumor was called eruptive epithelioid hemangioendothelioma with spindle cells. In our case, its development with recurrences and destructive features has some similarities to tumors of intermediate malignancy.

Abstract
BACKGROUND Specific cutaneous involvement is frequently observed in congenital leukemia and may be the inaugural sign. Lesions may be non-specific and even regress spontaneously, misleading diagnosis and delaying care. CASE REPORT A infant in good health had diffuse ecchymotic maculae at birth which totally regressed within 10 days. On day 20, a macular rash and three violet nodules developed. The physical examination found enlarged nodes, liver enlargement and poor general status. Blood cell counts and the myelogram led to the diagnosis of type 5 acute myeloblastic leukemia (AML 5). Search for extension revealed cutaneous leukemia and meningeal and renal involvement. DISCUSSION The predominance of myelocyte forms is specific for neonatal leukemia (AML 5 and 4). Specific skin lesions are frequent (25 to 30 p. 100 of cases) and sometimes precede (7 p. 100) anomalies in peripheral and medullary smears. Skin biopsy with direct smear can provide rapid diagnosis. Classically subcutaneous nodules or bluish macropapulae give the blueberry muffin baby aspect. The polymorphous features and the remarkably fluctuating skin lesions in our case are unusual, especially since the infant did not have spontaneously reversible neonatal leukemia, a rare unpredictable phenomenon described in newborns with a normal phenotype which can mislead therapeutic management.

Abstract
INTRODUCTION Excepting the endemic foliaceus form, childhood pemphigus is uncommon. We report two cases of pemphigus foliaceus in children with typical clinical manifestations. CASE REPORTS Case n(o) 1. A 5-year-old girl was seen for a vesiculobullous crusted dermatosis involving the trunk and the face which had developed over the last 5 months, predominantly in periorificial and fold localizations. Histology showed intragranulous acatholysis. Direct skin immunofluorescence was positive for anti-intercellular substance IgG and C3. Indirect immunofluorescence was positive for anti-intercellular substance antibodies at 1/500. The diagnosis of superficial pemphigus was retained and the child was given dapsone associated with systemic prednisone (1.5 then 2.5 mg/kg/d). Dapsone was stopped on day 15 due to poor hematological tolerance. Outcome was favorable allowing withdrawal of prednisone at 18 months. Case n(o) 2. A 6-year-old had developed since the age of 18 months a generalized and polycyclic pruriginous erythemato-squamous dermatosis with oozing discharge which started and predominated on the face (periorificial zones). Trace element (copper, selenium, zinc) and vitamin (A, E and B1) assays were within the normal range. Glucagon was normal. Histological examinations of several biopsies were non-contributive. Diagnosis of pemphigus foliaceus was finally obtained after repeated direct immunofluorescence tests which revealed anti-intercellular substance IgG. Indirect immunofluorescence was negative. The child was given prednisone (2 mg/kg/d). DISCUSSION In children, pemphigus foliaceus has an exceptional frequency and diagnosis is often made quite late (mean 8 months). The diagnosis should always be entertained in children who develop chronic extensive erythemato-squamous and crusted dermatosis, even if formation is absent. Direct skin immunofluorescence confirms the diagnosis and should be repeated if negative in cases with highly suggestive clinical presentations. It would be reasonable to attempt "minor" treatments as the first line approach. Systemic corticosteroids are however the treatment of choice despite the risk of classical side effects. Childhood pemphigus foliaceus is not an attenuated clinical form of adult pemphigus. Mortality is not negligible and is close to that in adults.
