The cause of leiomyomas is unknown. Several studies have suggested that each leiomyoma arises from a single neoplastic cell within the smooth muscle.

  Leiomyoma of the fallopian tube is extremely rare. Most cases are asymptomatic and may found incidentally at autopsy or during unrelated surgical operation. These leiomyomas tend to be singular, small, and unilateral, with a resultant rare preoperative diagnosis. They are often managed with laparotomy.

  We report a case of a fallopian tube leiomyoma in a 27- year- old virgin girl. She had abdominal pain. The mass diagnosed and treated by laparatomy. Microscopic examination revealed that it was a tubal leiomyoma.
