AbstractWe present a case of disseminated cutaneous histoplasmosis in a male patient, rural worker, HIV positive for 20 years, with a history of irregular use of antiretroviral therapy, T cell counts below 50 cells/mm3 and with good response to treatment with Itraconazole. We highlight importance of skin lesions in clarifying early diagnosis, since this co-infection often leads patients to death.

AbstractThe term "Wolf's isotopic response" describes the occurrence of a new skin disorder at the site of another unrelated and already healed skin disease. In most cases, herpes zoster is the inicial disease. Different disorders may develop on the same site, most commonly granulomatous and lichenoid reactions, infiltration of hematologic diseases, skin tumors and infections. There are few related cases of lichen planus presenting as isotopic response. We report a case of a 74 year-old woman, with multiple itchy, rose-colored and shiny papules that developed at site of previously healed herpes zoster, on the right arm and shoulder. The pathogenesis of this phenomenon is still unknown and further studies are needed.

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.

The authors study a patient carrying Aids, with exuberant dermatological manifestations of cryptococcosis. They stress the therapeutic effectiveness of short-term amphotericin B. The authors reviewed cases of cutaneous infection with Cryptococcus reported in the national and international literature, verifying that the frequency has increased with the AIDS epidemic. Also, they discuss about the differential diagnosis with some cases of dermatosis, particularly with the disseminated giant molluscum contagiosum. In relation to the therapy, they affirm that the choice of drug depends on the organ involved, as well as the immune state of the patient.Os autores estudam um paciente portador de SIDA, com manifestações dermatológicas exuberantes de criptococose. Destacam a eficácia terapêutica da anfotericina B, a curto prazo. Revisam os casos de criptococose cutânea relatados na literatura nacional e internacional, ressaltando o aumento de sua freqüência com a epidemia da SIDA. Também discutem o diagnóstico diferencial com várias dermatoses, particularmente com o molusco contagioso gigante disseminado. Em relação à terapêutica, afirmam que a escolha da droga depende do órgão comprometido, assim como do estado imunológico do paciente.

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.

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.

Os autores descrevem caso de baqueteamento digital, o qual possibilitou diagnóstico de carcinoma broncogênico em paciente assintomático. Baseados em levantamento bibliográfico, discutem sua fisiopatologia, associações com alterações sistêmicas e métodos para diagnóstico precoce, enfatizando sua importância, vista a associação do mesmo com várias doenças, incluindo neoplasias pulmonares.The authors describe a case of digital clubbing, which led to a diagnosis of bronchogenic cancer in an asymptomatic patient. Based on a review of the literature, we discuss its physiopathological aspects, associations with systemic conditions and recent methods for early diagnosis of digital clubbing. We emphasize the disease's importance in light of its association with several other diseases, including bronchogenic cancer.
