Disseminated toxoplasmosis as a cause of diarrhea.

Disseminated toxoplasmosis in patients with acquired immunodeficiency syndrome is often a central nervous system disease but may be seen as myocarditis or pneumonitis. Toxoplasmic colitis is a rarity. We report a case of toxoplasma colitis in a patient with diarrhea and hypokalemia. The microorganisms were identified in the colonic mucosa on H&E sections and confirmed by immunoperoxidase study.
