Abstract
Scalp seborrheic dermatitis (SSD) is a prevalent chronic, relapsing inflammatory skin disease. The etiology is related to sebum production, bacterial proliferation – <i>Staphylococcus</i> sp., <i>Streptococcus</i>, and <i>M. restricta</i> – and host immunity factors – NK1+, CD16+ cells, IL-1, and IL-8. Trichoscopy features include mostly arborizing vessels and yellowish scales. New trichoscopic findings were described to guide the diagnosis as dandelion vascular conglomerate, “cherry blossom” vascular pattern, and intrafollicular oily material. Antifungals and corticosteroids constitute the essential therapy, but new treatments have been described. This article aims to review and discuss the etiology, pathophysiology, trichoscopy, histopathologic findings, main differential diagnoses, and therapeutic options of SSD.

Abstract
Morbihan disease is a rare condition characterized by chronic and persistent erythematous solid edema localized on the face. It is believed to be a complication of rosacea and may occur at any stage of the disease. Features of this condition include variable therapeutic response and great refractoriness. We report a case of a 61-year-old man with rosacea history diagnosed with Morbihan disease, who showed excellent therapeutic response with the combination of deflazacort and oral isotretinoin but developed recurrence after corticosteroid discontinuation. We believe that in severe cases of lymphedema of the face this combination is effective and corticosteroid suspension should be done slowly and gradually.

Abstract
Blue nevi are benign melanocytic lesions located in the deeper reticular dermis, consequence of failure of melanocytic migration into the dermal-epidermal junction from the neural crest. Lesions are usually asymptomatic and solitary, but may present in a multiple or agminated (grouped) pattern. The agminated subtype is formed when bluish-pigmented lesions cluster together in a well-defined area. Lesions can be flat or raised. We report the case of a patient who presented multiple bluish macules (1-3 mm in diameter) grouped on the left upper back. Dermoscopy and anatomic pathological examination were consistent with blue nevus.

Abstract
Steatocystoma multiplex is a rare genetic disorder characterized by the presence of hamartomatous malformations at the junction of the pilosebaceous duct. It consists of encapsulated cystic lesions in the dermis, with adjacent sebaceous gland. When associated with inflammation, resembling hidradenitis, it is called steatocystoma multiplex suppurativa, a condition rarely reported. This is the first case of steatocystoma multiplex suppurativa reported in the Brazilian literature. Female patient, 23 years old, with papular and nodular cystic lesions that started in the armpits and groin, later spreading to the trunk, lower limbs, anticubital fossa, face and scalp. The presence of papular-nodular lesions associated with disseminated hidradenitis-like lesions in flexural areas and the histopathological diagnosis of steatocystoma defined the diagnosis of steatocystoma multiplex suppurativa.

Abstract
Granulomatous mycosis fungoides is a rare subtype of T-cell cutaneous lymphoma. Due to its clinical heterogenicity the diagnosis is delayed and based on histopathological and immuno-histochemical findings, sometimes requiring gene rearrangement studies for confirmation. We report the case of a patient who was submitted to several biopsies before diagnostic conclusion.

Abstract
Berardinelli-Seip syndrome is a rare autosomal recessive disease characterized by
inadequate metabolism and inefficient storing of lipids in fat cells, generating
accumulation of fat in organs such as the liver, spleen, pancreas, heart, arterial
endothelium and skin. Classically, patients manifest generalized lipoatrophy at birth
or until 2 years of age, and in adolescence usually develop marked insulin resistance
with rapid progression to diabetes and dyslipidemia. We report the case of a
17-year-old Berardinelli-Seip syndrome patient with eruptive xanthoma associated with
severe hypertriglyceridemia. It is worth noting Eruptive xanthoma as a dermatological
manifestation that is not generally highlighted in the reports of cases of this
genetic metabolic disorder.

Abstract
Dermatofibroma is a benign fibrohistiocytic tumor, common and easily diagnosed when
classical clinicopathologic features are present. The atrophic variant of
dermatofibroma is of uncertain origin. This lesion is characterized clinically by a
flat or atrophic and depressible surface. Histopathological features show reduction
of the thickness of the dermis and elastic fibers. We report a typical case of this
uncommon and probably underdiagnosed variant.

Abstract
Leprosy is an infectious disease with an average incubation period of two to five years. It is caused by Mycobacterium leprae, mainly affecting skin, mucous membranes and peripheral nerves. When it occurs in children under fifteen, it reflects an intense and long contact period, with a high bacillary load. Therefore, it is considered an important alert sign that points to the challenge of controlling the disease. The authors report three cases of leprosy in children under fifteen that occurred in the Itaguaí district, Rio de Janeiro. The epidemiologic implications of new cases detected at this age and the fundamental role of examining the patients' close contacts and the possible identification of source cases as an effort for leprosy control are discussed.

Abstract
Male patient, 28 years old, presented with an asymptomatic yellowish erythematous papule on his right thigh. Excisional biopsy was performed for histopathological examination of the lesion. Multinucleated cells (Touton giant cells) were observed. S100 immunohistochemistry was negative for CD1a and positive for CD4 and CD68. Based on clinical and histopathological findings associated with immunohistochemistry, we concluded that it was a case of adult-type xanthogranuloma. Because it was a solitary lesion without other clinical signs and symptoms, the medical conduct adopted was patient orientation.

Abstract
Hidradenitis suppurativa is a chronic inflammation of the apocrine glands. It usually starts at or soon after puberty, and women are more often affected than men. The most affected sites are the axillae; however, other regions rich in apocrine glands may also be affected. Involvement restricted to the inframammary fold alone is rare and to the best of our knowledge there have been no reports of any similar cases. The etiology of this condition has yet to be fully clarified.

Abstract
As acrometástases, principalmente para as mãos, são incomuns e representam cerca de 0,0070,2% de todas as lesões metastáticas. O pulmão é o sítio de origem mais comum, colaborando com 4050% dos casos relatados na literatura. Os rins e mamas são outras localizações também relacionadas a neoplasias que metastatizam para as mãos, além de, mais raramente, trato gastrointestinal, outros tumores sistêmicos e sarcomas. Seu diagnóstico precoce é difícil, pois pode ser assintomático, se assemelhar a tenossinovite, artrite, paroníquia, granuloma piogênico ou infecção local. No presente relato, os autores apresentam paciente com diagnóstico de acrometástase, em ambos os quartos quirodáctilos, oriunda de carcinoma basaloide de canal anal, com pobre resposta à radioterapia

Abstract
A hidradenite supurativa é doença inflamatória de difícil tratamento. Recentemente, a terapia anti-TNF alfa, com anticorpos monoclonais ("terapia biológica"), tem sido apontada como uma alternativa. No entanto, ensaios clínicos avaliando a eficácia destas drogas na hidradenite supurativa, ainda não foram publicados. Apresentamos um caso no qual o uso do infliximabe não resultou em melhora clínica expressiva.
