[Sacrum histoplasmosis 10 years after NHL of the sacrum: a case report]

The location of bone histoplasmosis is rare. It is a parasitic infection caused by Histoplasma capsulatum, affecting especially the immunocompromised. Diagnosis is difficult, requiring the use of mycological and histopathological studies. Through this observation, we report a rare sequence of the development of sacrum histoplasmosis in a patient treated 10 years ago for a malignant non-Hodgkin lymphoma of the sacrum with complete remission. The clinical and radiological investigations suggested a lymphomatous relapse but the pathological study showed histoplasmosis. Antifungal treatment was started with an encouraging evolution.
