Primary Transitional Cell Carcinoma of Fallopian Tube Mimicking Radiologically as Extrauterine Leiomyoma: A Case Report

Primary carcinoma of the fallopian tube is very rare among primary genital tract malignancies. Transitional cell carcinoma is among the rarest tumor subtypes that can involve the fallopian tube.
Here, we reported a 42-year-old premenopausal lady presenting with spotting, dysmenorrhea, and abdominal pain. She was found to have a pelvic mass in the right posterior cul-de-sac suspicious to be an eccentrically located leiomyoma. Histopathology examination of the resected mass revealed transitional cell carcinoma arising from the fallopian tube.
Primary fallopian tube tumors could be considered in differential diagnosis of pelvic mass and intraoperative frozen consultation is useful for correct diagnosis.
