Abstract
Squamous cell carcinoma (SCC) of the anal canal is very rare. We report a case of SCC of the anal canal that was found in the pelvis by abdominal CT. The tumor was 0-IIc type SCC of the anal canal and the depth was submucosa. The pathological diagnosis was moderately differentiated SCC. We surgically resected the tumor by abdomino perineal resection (APR). The number of 251 lymph node metastasis was detected.
