A great majority of endometrial carcinoma recurrences are observed in high-risk patients and within the first 3 years of treatment. The relapse of endometrial carcinoma occurring more than 10 years after initial treatment has rarely been described. Initially diagnosed and treated for International Federation of Gynecology and Obstetrics (FIGO) stage 1a, grade 1 adenocarcinoma, our patient presented 13 years later with an isolated pelvic recurrence, demonstrating, to our knowledge, the longest disease-free interval with recurrence in the pelvis reported in literature. After surgical resection, the patient is being considered for enrollment in a clinical trial. Despite favorable prognostic features, it is possible to observe the recurrence of endometrial carcinoma even 5 years after surveillance and remission. Successful salvage therapies are available but may depend upon early diagnosis.
