Malignant germ cell tumor of fallopian tube with rhabdomyosarcoma: a case report and literature review

Background Mixed germ cell tumors originating from the fallopian tubes are rarely reported, and high-grade rhabdomyosarcoma with differentiated components is even less common. The non-specific clinical manifestations of this tumor are prone to misdiagnosis, and there is still controversy over the treatment plan for this rare differentiated type, and there are limited reports on the prognosis of related diseases. Case presentation Here, we report a 34-year-old woman who presented to our hospital with abdominal pain for two weeks and aggravated for two days. After completing relevant examinations, she underwent transabdominal resection of large tubal masses on the left side of the tube + pelvic lymph node dissection + abdominal paraaortic lymph node dissection + right ovarian cyst excision + greater omentectomy + multipoint peritoneal biopsy. hematoxylin–eosin (H&E) and immunohistochemical (IHC) staining were performed on the surgically resected specimens to further determine the type and nature of the tumor, and 3 cycles of Bleomycin + Etoposide + Cisplatonum (BEP) chemotherapy and 1 cycle of EP(Etoposide + Cisplatonum) chemotherapy were given after surgery. Conclusion Up to now, regular follow-up of the patient's tumor markers and imaging showed no abnormalities, the general condition is good, and the tumor free survival time has reached 24 months.
