Isolated incisional recurrence in a patient with early-stage endometrioid carcinoma is extremely rare. The mechanism of this recurrence also remains unclear. We describe a case of an isolated incisional recurrence of endometrioid carcinoma from the uterine corpus 4 years after the primary surgery. We review the previous literature and discuss the possible mechanism of isolated incisional recurrence. A 56-year-old woman diagnosed with the International Federation of Gynecology and Obstetrics Stage IA and Grade 2 endometrioid carcinoma in the uterine corpus showed an isolated cystic mass in the abdominal wall 4 years after the primary surgery. She underwent resection of the abdominal tumor, and the pathological findings showed endometrioid carcinoma, which was the same as the primary tumor. She received chemotherapy and remained disease free 8 months after chemotherapy. Long-term follow-up is required to detect recurrence, even in patients with early-stage uterine corpus carcinoma.
