Abstract

Background: Malignant mixed mullerian tumor is an uncommon neoplasm of the female genital tract. The Fallopian tube is most uncommon site. Patients and Methods: The reported case corresponds to a 66 year old woman with abdominal pain. A total hysterectomy with bilateral salpingo-oophorectomy was performed. Results: The neoplasm distended and distorted the left Fallopian tube. On cut section the tube was filled and expanded by a soft tumor with hemorrhagic areas. Microscopically it was composed of malignant epithelial and stromal elements with foci of cartilaginous and rhabdomyosarcomatous differentiation. Conclusions: Four theories have been put forward to explain the origins of the Fallopian tube carcinosarcomas. C-erbB-2 over-expression in both epithelial and mesenchymal components suggests a common carcinogenic mechanism for both components and supports the conversion-histogenesis hypothesis implicating a dominant role for epithelial component.
