Abstract
Introduction/Background Primary peritoneal serous carcinoma is thought to arise from the peritoneum, however according the data fallopian tubes may be a source of many of peritoneal and ovarian carcinomatosis. Primary fallopian tube carcinoma is a rare. Often chronic tubal inflammation is associated with the primary carcinoma of the fallopian tube.
Methodology We presented a case of 29 year old women, who was admitted in gynecological department in December 2017 with lower abdominal and pelvic pain. Patient has 2 pregnancies in 2012 and 2016 and was delivered by cesarean section. During the bimanual examination, the normal size of the movable uterus and normal adnexa were detected. Transvaginal (TVS) ultrasound examination find a normal size ovaries, sausage-shaped cystic structure 4.7 x 4.4 x 3.9 cm on the right side and a small ovoid solid component 2.1x1.2cm and 1.9 x1.3cm in tubal angles of the uterus. A solid component was moderately vascularized on color Doppler ultrasound. CT scan were carried out and identified normal size ovaries with some calcification on the surface, disseminated, peptic, on the surface of the pelvic peritoneum. No other special findings were found. Diagnostic laparoscopy was performed.
Results A staging laparoscopy with multiple biopsy of suspicion lesions from surface of adnexal, peritoneum, colon, omentum and parametrical tissue performed. Frosen section and final histological examination combined with immunohistochemical investigation has confirmed primary tubal low grade G1 serous carcinoma. A patient referred for future treatment and follow-up.
Conclusion Often primary fallopian tube cancers may misdiagnosed as primary ovarian cancers, however experienced pathologist can helps to correlate the ultrasound findings and to differentiate primary fallopian carcinoma. According to literature ultrasound findings of a vascularized sausage-shaped structure with an ovoid solid components in the pelvis with moderate or sever vascularization should raise the suspicion of tubal cancer, especially if normal ovarian tissue identified.
Disclosures None.
