PURE EMBRYONAL RHABDOMYOSARCOMA OF THE FALLOPIAN-TUBE

Rhabdomyosarcoma is a neoplasm of childhood which commonly arises in t he genitourinary tract. Reported locations include the bladder, prosta te, paratestis, vagina, uterus, cervix, and ovary. Rhabdomyosarcomas h ave been reported to occur in the fallopian tube only as a component o f a malignant mixed mullerian tumor. We present a case of pure embryon al rhabdomyosarcoma of the fallopian tube in a 17-year-old. The diagno sis was confirmed by immunohistochemical stains. The strongest evidenc e for the primary location of this pure embryonal rhabdomyosarcoma was the gross appearance of the tumor at laparotomy. Additionally, rhabdo myosarcomas arising from adjacent organs have never been reported to g row into the fallopian tubes. (C) 1997 Academic Press.
