Histoplasmosis due to Histoplasma capsulatum var duboisii in a Canadian immigrant

Abstract

Histoplasmosis due to Histoplasma capsulatum var duboisii developed in a Canadian immigrant one year after his entry into Canada. He had lived in Guinea for two years prior to immigration. Lymphatic infection characterized the course of his illness. The clinical and pathologic features of this disease's distinctive skin and bone manifestations are outlined. The causal agent's mycologic features are compared with those of H capsulatum var capsulatum. Treatment with amphotericin B was successful.
