[Oral histoplasmosis].

Histoplasmosis is a deep mycosis which occurs in America and Africa. It is extremely rare in France. The case presented involves a male subject who had spent time in the French colonies of Africa and in Brazil. He presented with undiagnosed ulceration of the cheek, similar to that seen with cancer. Diagnosis was made on histology on one hand and on mycological examination on the other. This case serves to remind us that tropical and sub-tropical pathology may be encountered in temperate zones due to population migration.
