Leiomyosarcomas (LMS) of the ovarian vein are extremely rare and have a poor prognosis. Only 10 cases have been reported since 1977. The patient is a 69-year-old woman presented with right abdominal pain. Computed tomography showed a regularly shaped tumor, 80 mm in diameter in the retroperitoneum, adjacent to the descending part of the duodenum. Intraoperatively, the right ovarian vein was found to run through the tumor and was, therefore, resected together with the tumor. Pathological examination revealed a LMS of the right ovarian vein. Nine months postoperatively, multiple lung metastases were detected and chemotherapy was initiated. Delayed diagnosis is associated with high mortality. It is important that the diagnosis of LMS should be made preoperatively when you have already diagnosed a tumor to better direct the surgical approach. Multimodal therapy may improve prognosis.
