title: Metastatic large intestinal adenocarcinoma in two rhesus macaques (Macaca mulatta).
abstract: Spontaneous colonic adenocarcinomas were diagnosed in two rhesus macaques (Macaca mulatta). Although both tumors caused partial obstruction of the colon, they were histologically different. One resembled the commonly described "napkin-ring" adenocarcinoma similar to those found in the descending and sigmoid colon of humans. The other neoplasm, a "tubular" lesion, invaded the full thickness of the colonic wall at the ileocecal-colonic junction. Both tumors were associated with metastasis, which is uncommon in the rhesus monkey.
