Rectal metastasis of sigmoid colon cancer
preprint
OA: closed
Abstract
A 73-year-old man underwent a stage Ⅱ sigmoid colon cancer resection. Careful monitoring was undertaken, and no evidence of metastasis or anastomotic recurrence was noted until 51 months later. Anal examination revealed a pink, firm perianal tumor histologically identified as a metastasis of the colon adenocarcinoma.
