A Case of Extramurally Growing Rectal Cancer

Abstract

A 73-year-old woman was admitted to the hospital because of discomfort after defecation and stools with slime and blood-streaking.Rectal cancer was the most likely diagnosis clinically, but no definite diagnosis of rectal cancer could be achieved even by four times of biopsies. To improve the patient's quality of life, only stoma was created. Thereafter the patient's disease progressed to its termination, and extramurally growing rectal cancer was definitely diagnosed at autopsy.Colorectal cancer which exhibits the progressive pattern of forming a tumor extramurally has been reported in 25 cases in Japan. Of these 25 cases, only three cases were of rectal cancer, but the presence of such cases showing the special growing pattern like in this case must be kept in mind and deal with.
