Abstract
We report a case of cecal adenosquamous carcinoma. An 81–year–old woman admitted for right abdominal pain and constipation and treatment for an ascending colon tumor was found in computed tomography (CT) to have a type 2 tumor diagnosed pathologically as well–differentiated adenocarcinoma. Operative findings showed a tumor 11cm in diameter invading the transverse colon from the ascending colon to the cecum, necessitating right hemicolectomy with lymph node dissection. The final diagnosis was SI, ly2, v1, N0 (0/23), PM0, DM0, RM0, fStage II, curA. The histological type was adenosquamous carcinoma. No indications of recurrence have been seen in the 84 month (12 years) since surgery. of No adjuvant chemotherapy was done. Pathological findings suggest that adenosquamous carcinoma may be squamous differentiation from adenocarcinoma.
