Primary oral histoplasmosis in India

The histopathology and mycology of histoplasmosis restricted to the oral mucous membrane in an Indian patient, who had never gone outside the country, are described. The yeast form of Histoplasma capsulatum was transferable experimentally to mice by successive intraperitoneal inoculations. The infectivity of the disease, the extrapulmonary symptoms in most of the Indian histoplasmosis cases and the source of infection in India are discussed.
