Endometriosis within a perineal scar after a Miles' procedure has not been previously reported in literature. We report a case of a 35-year-old-female who was treated 10 years before at the same institution for a low rectal cancer that presents with two discrete subcutaneous bulges within her perineal wound. Since the patient was asymptomatic and the complete work up for recurrent disease showed no evidence of malignancy, first line therapy was conservative. After two pregnancies and a caesarean section, the patient presented at our observation with enlarged and tender perineal nodules. The patient was treated with a wide excision of the perineal scar en-bloc with the nodules. Final pathology report was consistent with scar endometriosis.
