[Case of lipohyperplasia of the ileocecal valve with adenocarcinoma of the ascending colon].Gan No Rinsho. 1983 Oct; 29(12):1476-9.GN
A rare case of lipohyperplasia of the ileocecal valve contiguous with adenocarcinoma of the ascending colon is reported. The patient was a 67-year-old female with a chief complaint of muco-bloody stool. Barium enema X-ray study revealed a filling defect in the proximal portion of the ascending colon, suggestive of Borrmann II-type carcinoma and enlargement of the ileocecal valve. Ileocecotomy and right colectomy were performed. Histological examination disclosed that the tumor of the ascending colon consisted of well differentiated adenocarcinoma; the proliferation of fat tissue in the submucosa of the ileocecal valve was diagnosed as lipohyperplasia of the ileocecal valve. The histogenesis of this lipohyperplasia seems to be secondary development induced by the adenocarcinoma of the ascending colon.
