Hand metastases occur infrequently, and metastatic tumors in the soft tissue of the hand caused by rectal cancer are extremely rare. We report a case here. The patient was a 76-year old man. He underwent Miles operation for rectal cancer located in the lower portion of the rectum. Histopathologically, the resected specimen showed well-differentiated adenocarcinoma. Six years postoperatively, a tumor involving the soft tissue of the palma was found in his left hand. The tumor was resected, and pathological examination showed a well-differentiated adenocarcinoma similar to the primary rectal carcinoma. Immunohistochemical examination demonstrated that this hand tumor had metastasized from rectal cancer. Fifteen cases of colorectal metastatic tumors in the hand have been documented, of which three were soft-tissue metastases. This report describes the fourth case.
手部转移瘤很少见，直肠癌导致的手部软组织转移性肿瘤极为罕见。我们在此报告一例。患者为一名76岁男性。他因直肠下段的直肠癌接受了腹会阴联合切除术。组织病理学检查显示，切除标本为高分化腺癌。术后六年，在他的左手发现一个累及手掌软组织的肿瘤。该肿瘤被切除，病理检查显示为与原发性直肠癌相似的高分化腺癌。免疫组化检查表明，这个手部肿瘤是由直肠癌转移而来。文献记载了15例手部结直肠转移性肿瘤，其中3例为软组织转移。本报告描述的是第四例。
