[Cutaneous lesions of bilharziosis. Report of fourteen cases (author's transl)].

The cutaneous localization of bilharziosis are infrequent. In a country of endemic disease, the Ivory Coast, where about 10 p. 100 of the population suffer from bilharziosis, it has been observed, between 1970 and 1980, 14 cases of cutaneous bilharziosis which have been diagnosed by micropathology. These lesions appear as papules or lichenoid plaques, usually clustering around umbilicus and upper dorsal regions. They require the presence of living eggs which induce the formation of a granuloma called "bilharziosis follicle", within which bilharziosis eggs are discovered. This reaction is explained by delayed hypersensitivity against soluble antigens of the eggs. The treatment is that of bilharziosis.
