摘 要：It is difficult to distinguish a rectal carcinoma with anal metastases from coexistent synchronous anorectal *** therapeutic strategy for rectal and anal carcinoma is so different that it should be clearly ***,we report on the case of a 63-year-old man who presented with an upper-third rectal *** months after resection,he developed an adenocarcinoma in the anal *** histological slides of both tumors were reviewed and immunohistochemical studies for cytokeratins(CKs)7 and 20 were *** index tumor demonstrated CK 7–/CK 20+and the second showed CK7+/CK20+.For this reason,we believe the present case had synchronous adenocarcinomas arising from anal canal and the rectum *** is very important to differentiate the anorectal lesions pathologically because of the impact on the therapeutic options available,especially for the lesion arising in the anal canal.
