Gastrointestinal histoplasmosis.

Histoplasma capsulatum involves some part of the gastrointestinal tract in 75% of patients with disseminated disease, but clinically obvious gastrointestinal involvement is infrequent. Symptoms include crampy abdominal pain, diarrhea, nasopharyngeal ulcers, and rectal ulcers. Granulomatous constrictive lesions may simulate either carcinoma anywhere in the gut or less commonly Crohn's disease. We describe a patient and discuss gastrointestinal histoplasmosis.
