Extraskeletal myxoid chondrosarcoma mimicking mucinous ovarian cancer: A case report

AbstractPelvic masses can represent various etiologies, including gynecologic and non‐gynecologic conditions. As discussed in this paper, among all pathologies, intraabdominal dissemination of an extraskeletal myxoid chondrosarcoma (ESMC) presenting as a pelvic mass is a rare condition. The case is a 58‐year‐old woman with a history of soft tissue sarcoma who presented to the gynecologic oncology department with a pelvic mass and was operated on with the suspicion of mucinous ovarian cancer. She underwent complete cytoreductive surgery, and her final pathology was reported as ESMC. Due to several numbers of metastases shown in positron emission tomography‐computed tomography, she had chemotherapy and then operated on for tumorectomy from the right leg. ESMC is a rare, aggressive soft tissue neoplasm that rarely has metastasis to the abdomen. This unique case presents a late recurrence of the disease to the pelvis, which can mimic mucinous ovarian cancer.
