We present a case of colonic histoplasmosis in a young HIV antibody-positive homosexual male who presented with acute diarrhea. The diagnosis was made by flexible sigmoidoscopy with biopsy which revealed organisms morphologically consistent with Histoplasma capsulatum, and was later confirmed by fungal culture of the biopsy specimens. At colonoscopy, skip areas with plaques, ulcers, and a pseudopolyp were observed. The colitis resolved endoscopically after a 6-wk course of intravenous amphotericin B, and the patient has had no recurrence of symptoms while on maintenance therapy with amphotericin B. However, the organisms continue to be noted on biopsies of normal-appearing areas in the rectum and sigmoid 5 months after diagnosis. Colonic involvement with H. capsulatum, an organism endemic to the Midwest, may be seen more frequently as the total number of cases of HIV-infected individuals increases in this region.

The authors report the case of a 45-year-old HIV and HTLV1 antibody positive male patient form French West-Indies who was infected by disseminated histoplasmosis presenting as acute diarrhea. Esophagogastroduodenoscopy revealed gastric mass and colonoscopy patchy erythematous mucosa. The diagnosis was made by histology of bone marrow specimens, upper gastrointestinal tract and colon biopsies, and late skin lesions. Initial therapy with amphotericin B and itraconazole was successful, but maintenance therapy with itraconazole alone did not prevent relapse and a fatal outcome. Disseminated histoplasmosis in AIDS patients may be present as gastrointestinal manifestations and should be kept in mind in non endemic areas such as the French West Indies.
