One case of squamous cell carcinoma of the ascending colon is reported. The patient, a sixty two year old woman, was admitted because of right abdominal pain for three months. A mass, 6 X 5 cm in size, was palpated. 13 cm colonic mucosa destruction was shown by barium enema. Right hemicolectomy was done. A squamous cell carcinoma of the ascending colon was diagnosed by light and electron microscope. Squamous cell carcinoma of the colon is rare. Squamous cell carcinoma and adenoacanthoma, occurring in the colon and upper rectum, comprise 0.5% of all colonic malignancies. 18 cases have been collected in the literature and this case is the first one reported in China. Etiology of squamous cell carcinoma of the large bowel is reviewed.
