Case Report: Unpredictable Nature of Tubal Cancer

Abstract Introduction Primary tubal cancer is very rare, most are diagnosed intra and post operatively. Histopathology is vital in determining the cancer origin. Here we present a case of fallopian tube cancer with clinical presentation mimicking endometrial origin. Case description A 74-year old patient came with complaints of intermittent post-menopausal bleeding and pelvic pain. The patient had several investigations using Ultrasonography, Hysteroscopy-guided biopsy, and Magnetic Resonance Imaging. Pre-operative diagnosis was endometrial cancer based on histopathology of endometrial biopsy during hysteroscopy. Explorative laparotomy, total abdominal hysterectomy, bilateral salphingo-oophorectomy, pelvic and para-aortic lymph node dissection were then performed, and the tumor samples were sent to the histopathology laboratory. It was found that the post-operative diagnosis was in fact primary fallopian tube cancer stage IIB. Conclusion For patients with gynecological malignancies, rare cases such as fallopian tube cancer should never be overlooked as a differential diagnosis.
