ALCANTARA FIGUEROA, Christian  and  SANCHEZ CERNA, Víctor. Colon and rectum histoplasmosis in a patient from Peru. Rev. gastroenterol. Perú [online]. 2016, vol.36, n.4, pp.365-368. ISSN 1022-5129.

We report a case of a male patient of 52 years old with a 3 months history of pushing, tenesmus, hematochezia, pain while defecating, lost of 18 kg of weight, fever, fecaloid and purulent discharge through an perianal hole. During the colonoscopy procedure, we found many ulcers in the ascending, transverse and descending colon.We also found an elevated lesion of about 5 cm in the rectum. We used hematoxylin - eosin and Gomori-Grocott stain in the biopsies and identified many microorganisms inside macrophages which were compatible with histoplasmosis. ELISA tests for HIV, HTLV I- II were negative. Colon and rectal histoplasmosis in an immunocompetent patient is extremely rare. There are few cases of colonic histoplasmosis reported.
