[Colitis caused by cytomegalovirus in acquired immunodeficiency syndrome. Report of 2 cases of autopsy].

Two autopsy cases of CMV colitis in AIDS are reported. Intestinal manifestations lasted 2 and 5 months in each case and included: diarrhea and abdominal colic pain. The causes of death were: disseminated CMV infection in case 1 and miliary tuberculosis in case 2. In case 1 small ulcers were apparent in the ileum and the cecum. Microscopic foci of necrosis were also observed. Case showed: sigmoid dilatation with mucosal hemorrhages, small acute ulcers and submucosal fibrosis in the transverse portion of the colon. In both cases cytomegalic inclusion bodies within the endothelial cells of the capillaries at the bottom and the margin of the ulcers were observed. We compare our findings with those in other recently published cases.
