Twenty-five year old male patient presenting with asymptomatic brown spots, on cervical, axillary, inguinal and popliteal regions, for the last nine months. Pathological examination showed hydropic degeneration of the basal layer, pigmentary incontinence and moderate inflammatory lymphocytic infiltrate in the dermis. Lichen planus pigmentosus inversus is a rare subtype of lichen planus characterized by hyperchromic, asymptomatic or mildly pruritic macules, measuring from millimeters to centimeters in diameter, with defined borders, affecting intertriginous areas, most commonly in the axillae and groin of Caucasian patients. It presents unique lichenoid histology. We report a case with typical clinical features, histology and evolution.

Propylthiouracil (PTU), a thyonamide class drug commonly used to treat hyperthyroidism has been reported to cause adverse reactions in 3% to 12% of patients. The side effects have been described more frequently as mild, but ocasionally severe fatal reactions may occur. We report the case of a fourteen years old patient in use of PTU for the last three years who presented with fever, hemorrhagic blisters, necrotic ulcers, and that developed purpuric lesions and nodules in lower extremities. Laboratory and histopathologic findings were compatible with skin leukocytoclastic vasculitis, a pattern found in hypersensitivity reaction vasculitis. Suspension of PTU and introduction of prednisone, induced complete remission of symptoms and healing of the skin lesions. The importance of this study is to call attention to the occurrence of serious cutaneous manifestation with a mortality rate that might reach 10%, associated with a systemic drug frequently used in internal medicine. Early diagnosis and withdrawal of the suspected medication is mandatory. Administration of corticosteroids and/or immunosuppressives agents must be considered.

Granuloma anular (GA) é uma dermatose benigna, caracterizada em geral por lesões papulosas em disposição anular. As formas clínicas englobam GA localizado, GA generalizado, GA perfurante e GA profundo. É de etiologia desconhecida, apesar de diversos fatores serem incriminados, inclusive doenças auto-imunes. Apresentamos o caso de paciente masculino de 45 anos, com lesões dermatológicas características de GA localizado, associadas a alterações sistêmicas, cuja investigação diagnóstica demonstrou tratar-se de hipertireoidismo por Doença de Graves. O paciente foi submetido a tratamento endócrino e dermatológico com controle do quadro clínico. A inusitada associação do GA localizado com hipertireoidismo, não encontrada na literatura médica, nos estimulou a publicar este caso.

Cutaneous metastasis is a phenomenon that results from a tumor spreading via lymphatic or vascular embolization, direct implant during surgery or skin involvement by contiguity. The primary malignant tumor that most commonly metastasizes to the skin in women is breast cancer, which can be manifested through papulonodular lesions, erysipeloid or sclerodermiform infiltration, en cuirasse. We report the case of a female patient, 78 years old, with papular, scaly and confluent lesions in the right breast for one year, progressing to edema and skin infiltration, reduction of breast volume and plaque en cuirasse, and similar lesions in the contralateral breast and abdomen for four months. The pathological diagnosis was invasive ductal breast carcinoma with Paget-like foci, epidermal skin metastases and lymphatic embolization. A metástase cutânea é conseqüente à disseminação do tumor por embolização linfática, vascular, implantação direta durante cirurgias ou envolvimento da pele por contiguidade. Em mulheres, o tumor maligno primário que mais comumente metastatiza para a pele é o de mama, que tanto pode se expressar por lesões tumorais papulonodulares, infiltração erisipelóide ou esclerodermiforme, em couraça. Relatamos o caso de paciente do sexo feminino, 78 anos, apresentando lesões nodulares, descamativas e confluentes em mama direita, evoluindo com edema e infiltração cutânea, com redução do volume mamário e placa endurecida ilimitada. Invasão da mama contralateral e abdome ocorreram 4 meses após o início dos sinais. O diagnóstico histopatológico foi de adenocarcinoma ductal invasivo de mama com focos pagetóides epidérmicos e embolização linfática.

Childhood Granulomatous Periorificial Dermatitis is an acneiform facial rash that affects the periorificial area in children. The clinical aspectare asymptomatic 1-3 mm papules of, monomorphic, erythematous or hypopigmented in periorificial areas - mouth, nose and eyes. It's a benign and self-limited disease that heals spontaneously without scarring and specific therapy. Differential diagnoses include perioral dermatitis, granulomatous-rosacea, sarcoidosis, and lupus miliaris disseminatus faciei. We present the case of a 4-year-old boy, presenting papules in periorificials areas. Due to its low incidence and low number of publications we report the present case.

Glomus tumor is a painful tumor derived from the glomus terminal which regulates blood circulation and body temperature Despite its rarity, particular attention needs to be paid to symptoms associated with this tumor: paroxysmal pain, sensitivity to local pressure and cold, and its location - typically in the distal phalanx. Manifestation of extradigital occurrence is possible. Single lesions are most common in adult females, while multiple lesions are prevalent in children and adolescents, generally those with a positive family history. The diagnosis is clinical with the aid of ultrasonography and magnetic resonance imaging, confirmed by histopathological examination.

Report on the case of a patient with a combination of multiple uterine and dermatoleiomiomas and uterine miomatosis of long evolution. It is a rarely diagnosed disease known as Reed's syndrome. The study highlights the requirement for, and importance of, systemic investigation for kidney cancer, which is related to the syndrome.

Marjolin's ulcer is a term used to describe a malignant transformation that originates in chronic skin lesions. These neoplasms may be more aggressive than those unassociated with healing processes and are frequently overlooked or inadequately treated. This case report describes the occurrence of a squamous cell carcinoma occurring at the site of a burn scar and emphasizes the need for early diagnosis and treatment in order to assure better prognosis.

Scleredema of Buschke (SB) is a rare disorder of connective tissue, characterized by hardening of the skin. Of unknown etiology, it may be associated with viral or bacterial infections, hematological alterations and diabetes mellitus (DM). In half of the reported cases of SB, there is association with DM. The most common characteristics among these patients are: being male adults, having long-term DM, bad metabolic control and presence of specific complications of DM. The histopathological examination shows dermal thickening, with widened collagen fibers separated by non-colored spots, which correspond to mucopolysaccharides deposits. The clinical consequences are: decrease in motility of the shoulders and an impairment of respiratory function. Several treatments are suggested in the literature, but with inconstant results. A case of SB is reported in a type 2 diabetes patient.

Granuloma annulare (GA) is a begin dermatosis characterized, in general, for papular lesions with annular configuration. Its clinical forms comprehend localized GA, generalized GA, perforating GA and subcutaneous GA. With unknown etiology many factors have been responsible, including autoimmune diseases. We describe a case of a 45-year-old man, with characteristic dermatological injuries of localized GA, associated to systemic alterations, compatible with hyperthyroidism (Graves disease). The patient was submitted to an endocrine and dermatological treatment with control of the clinical state. The unusual association of localized GA with hyperthyroidism, not found in the medical literature, stimulated us to publish the case.

Potassium hydroxide (KOH) is a strong alkali that has long been known to digest proteins, lipids, and most other epithelial debris of skin scrapings to identify fungal infections. To our knowledge, KOH has never been used for the treatment of molluscum contagiosum (MC). We evaluated 35 children with MC for the clinical effectiveness of treatment with topical 10% KOH aqueous solution. The solution was applied by the parents of affected children, twice daily, on each MC lesion. The therapy was continued until all lesions underwent inflammation and superficial ulceration. Thirty-two of 35 patients achieved complete clinical cure after a mean treatment period of 30 days. Three children discontinued treatment: two reported severe stinging of the lesions and refused further applications; the other, with giant MC lesions, developed a secondary infection with prolonged treatment. Therapy with KOH was found to be effective and safe in the treatment of MC in children.

Es wurde der Einflus verschiedener Fettlosungsmittel auf die Durchlassigkeit der Gesamt-Hornschicht fur Wasser untersucht und festgestellt, das die Permeation in die Haut unter den gewahlten Versuchsbedingungen zunimmt (auf rund 150% der Normalwerte im Falle von Ather, Aceton bzw. Athanol + Ather). Weiterhin wurde gefunden, das die aus der Haut austretenden Wassermengen nach Entfettung der Haut unerwarteterweise unter den Normalwerten liegen. Ruckfettung der atherextrahierten Haut mit verschiedenen kunstlichen Fetten senkte die Permeationswerte in beiden Richtungen unter die Normalwerte.
