Introduction: Surgical management of patients with multiple metastases from mucinous rectal carcinoma is feasible.
Case description: We present a case of a 66-year-old woman with a late onset of peritoneal and coccygeal metastasis from a mucinous rectal carcinoma treated with cytoreductive surgery. After 30 months from rectal resection, the patient underwent exploratory laparotomy with resection of all tumor localizations by means of pelvic peritonectomy, complete supracolic omentectomy, jejuneal resection, appendectomy, and excision of the mobile part of the coccyx.
Conclusion: This report aims to point out the atypical late-onset recurrence presentation and management of a mucinous carcinoma of the rectum.
