Partial molar pregnancy as ruptured tubal ectopic.

Tubal molar pregnancy is extremely rare, and less than 200 cases have been reported in the literature. The incidence is approximated at 1.5 per 1 000 000 pregnancies. We report a case of ruptured tubal pregnancy in a woman, whose postoperative histopathology diagnosis showed partial molar pregnancy in the ruptured fallopian tube. The presence of abnormal, non-polar trophoblast proliferation, which is circumferential with vacuolation, along with sheets of pleomorphic extravillous trophoblast, is the main diagnosing feature, and it carries the risk of malignant potential.
