Prostatic abscess due to Histoplasma capsulatum in a patient with the acquired immunodeficiency syndrome.

Disseminated histoplasmosis is a systemic fungal infection that may occur in previously healthy or immunocompromised patients. The condition is being recognized with increasing frequency in persons infected with the human immunodeficiency virus. The most common organs involved include the lung, bone marrow, lymph nodes, liver, adrenals and central nervous system, with genitourinary involvement being exceedingly unusual. We describe a Histoplasma capsulatum prostatic abscess occurring after therapy for pulmonary histoplasmosis in a patient with the acquired immunodeficiency syndrome. The prostate may be a difficult focus from which to eradicate disseminated fungal infection in immunocompromised patients.
