Abstract:

Primary carcinosarcoma of the fallopian tube is a rare malignant tumor originating from mesodermal tissues. Its etiology and pathogenesis remains unclear, and surgical treatment is the main clinical approach. We report a case of primary carcinosarcoma of the fallopian tube with extensive omental metastasis. The patient underwent pelvic magnetic resonance imaging because of abdominal pain, which revealed a large solid pelvic mass accompanied by enlarged bilateral iliac vessels and para-aortic lymph nodes. After multi-disciplinary discussion, the patient underwent transabdominal pelvic mass resection, total hysterectomy, omentectomy and appendectomy, pelvic lymph node dissection, and tumour cytoreduction surgery. After the operation, the patient received one cycle of intravenous chemotherapy with paclitaxel combined with carboplatin. Due to intolerable myelosuppression after chemotherapy, the patient signed out of the hospital and passed away according to telephone follow-up. By summarizing the onset characteristics, histopathological manifestations, diagnosis, treatment and prognosis of tubal carcinosarcoma in this case, we aim to improve clinicians′understanding of this disease and provide references for its clinical diagnosis and treatment.
