Primary carcinoma of the fallopian tube; report of two cases.

Primary fallopian tube carcinoma (PFTC) is a rare tumor that histologically and clinically resembles epithelial ovarian cancer. PFTC has a worse prognosis than ovarian cancer as it is not routinely suspected and so treatment may be delayed. The early clinical manifestations and a prompt investigation can often lead to a correct diagnosis at an early stage. The preoperative diagnosis is usually difficult, and most patients with PFTC undergo laparotomy with the presumed diagnosis of ovarian carcinoma according to the presence of an adnexal mass. PFTC can present preoperatively as a tubo-ovarian abscess and it should be considered in the differential diagnosis of acute pelvic peritonitis. PFTC should be suspected by clinicians even if the presenting symptoms are atypical. We report here on two cases of PFTC along with a brief review of the literature.
