[Chromomycosis].

A case of chromomycosis with an evolution of 25 years, in a caucasoid man, aged 57, living in Mozambique, is reported. Fonsecae pedrosoi, the most frequently responsible agent of chromomycosis in Mozambique's cases, was isolated. Prognosis seemed poor since good results from therapy were unexpected, considering the long course of disease, the extensive and fibrotic lesions, and the unsuccessful treatment with 5-fluorocytosine and ketoconazole. The patient was treated with associated amphotericin B-5-fluorocytosine, and topical heat. Clinical improvement and mycologic negative studies were obtained.

[Persistent acantholytic dermatosis].

A 43 years old male patient with a pruritic, papular and papulovesicular eruption of 8 years duration is reported. The lesions come in crops (4-5 a year) of variable duration (4 days a 2 months) and are not influenced by treatment except, perhaps, systemic corticotherapy. Histologically there is focal acantholysis of limited extension but often involving the whole thickness of the stratum malpighi. The relationships between the persistent and the transient varieties of Greover's disease are discussed as well as the ones with cutaneous diseases in which focal acantholytic dyskeratosis has been observed.

[Congenital psoriasiform erythroderma with bullous eruptions].

A 39 years old female patient with congenital erythroderma is reported. The condition was considered as the non bullous type of Brocq's congenital ichthyosiform erythroderma until recently. The patient was admitted as she had generalized erythema, desquamation and oedema, pyrexia and oliguria. The scales were fine and small, quite different from those of lamellar ichthyosis. The patient developed a recidivant pustular eruption on palms, face and trunk. So the diagnosis was changed to congenital psoriasiform erythroderma and this was supported by histopathological examination of both scaling and pustular lesions. There was a remarkable improvement on amethopterin therapy. The case is discussed and the relevant litterature is reviewed.

[Spotted fever in the municipality of Pedreira, PS, Brazil. Serologic survey].

Cases of Brasilian spotted fever (BSF) have been occurred since 1985, in the rural area of Pedreira town, situated 160 km away from the city of São Paulo (longitude 46 degrees 54'07", latitude 22 degrees 44'21"). Aiming at evaluating the prevalence of Brasilian spotted fever in this endemic area, single-serum samples were collected from 473 healthy persons, amongst city-dwellers and the local china industry workers. The obtained samples were tested by indirect immunofluorescence (IFA), in order to determine the antibodies titer for the group of Brasilian spotted fever. Twenty-five (5.3%) were considered positive (titer 3 1:64) and thirty-one (6.5%) were taken as "borderline" (titer 1:32). The results show a serologically positivity rate similar to other areas, known as endemic ones within the country.
