ABSTRACT
A study was carried out to identify Leishmania species involved in skin lesions of patients from Cosmópolis and Indaiatuba, State of São Paulo, Brazil. The epidemiological data of cutaneous leishmaniasis in two cities suggested a epidemic situation in 1994. The lesions were clinically characteristic of cutaneous leishmaniasis and five out six patients responded positively to Montenegro's intradermal test. The histopathology of skin lesions were characterized by two patterns: exudative-cellular reaction and exudative granulomatous reaction. The clinical and histopathological parameters suggested Leishmania (Viannia) braziliensis as the possible etiologic agent. In agreement, it was difficult to isolate and maintain the parasite in the laboratory. Characterization by in situ hybridization with kDNA amastigotes from lesions fragments confirmed that Leishmania (Viannia) braziliensis was the parasite responsible for the studied cutaneous lesions.

Os autores descrevem dois casos de pele decidua, provavelmente os primeiros assinalados no Brasil desta rara genodermatose que parece ser de transmissao hereditaria autossomica recessiva. Sao analisados os aspectos clinicos, a possivel interferencia climatica sobre sua evolucao e os achados histopatologicos, sendo comparados todos esses dados com a escassa literatura publicada sobre a doenca

Apresenta-se o relato de um caso de zigomicose subcutanea, micose rara, descrita em algumas regioes tropicais. No Brasil o maior numero de casos foi descrito no estado da Bahia.Sao feitas consideracoes sobre a doenca, comparando-se com os achados do presente caso. Neste, e admitida a possibilidade do vetor mecanico ter sido o anelidio vulgarmente chamado "sanguessuga" (Gen Hirudo)

A case of Abrikossoff's granular-cell tumor is reported because of its unusually large dimensions (12.5 X 10.5 X 8.0 cm.), weight (700 g.) and supra-umbilical localization. Ample surgical excision of the tumor and reconstruction of the abdominal wall with silastic and skin graft were performed. Comments are made about the clinical, histopathological and histogenetic aspects of the neoplasia.

Sao relatados quatro casos de elastose perfurante serpiginosa, ocorridos em jovens brancos, de 12 a 16 anos. Dois pacientes eram do sexo masculino e dois do feminino.O inicio da molestia ocorreu nas idades de tres a 12 anos A evolucao variou de dois a 13 anos. As lesoes eram eritemato-papulosas, ceratosicas e tinham disposicoes arciforme e serpiginosa.Raramente eram isoladas. Em todos os casos as lesoes se localizaram nos membros superiores.Um dos pacientes apresentava tambem lesoes nos joelhos e coxas.Em um caso havia associacao com alopecia ofiasica e monogolismo ou sindrome de Down e em outro com nevo pigmentado congenito gigante da regiao peitoral direta. Foram abordados alguns aspectos histopatologicos e patogeneticos da afeccao
