Granulomatous Hepatitis Secondary to Histoplasmosis in an Immunocompetent Patient.

Histoplasma capsulatum is the most common endemic mycosis in the United States and usually occurs in certain geographic areas, such as the Mississippi or Ohio River valleys. Histoplasmosis usually causes a mild disease in the immunocompetent but can progress to disseminated disease in patients with impaired immunity. Granulomatous hepatitis as a manifestation of disseminated histoplasmosis in immunocompetent patients is extremely rare. We report the case of a 62-year-old immunocompetent gentleman with a history of histoplasmosis who presented with abdominal pain, elevated liver enzymes, who was diagnosed with granulomatous hepatitis secondary to histoplasmosis.
