Ruptured Partial Tubal Molar Pregnancy: A Case Report and Literature Review

Gestational trophoblastic diseases (GTDs) encompass a spectrum of clinical conditions characterized by significant polymorphic features in their clinical presentation and biological behavior, along with a potential risk for malignant transformation. Ectopic molar pregnancy, specifically the partial tubal subtype, is an exceptionally rare clinical entity that poses significant diagnostic challenges. We report the case of a ruptured partial tubal molar pregnancy in a patient presenting with an acute surgical abdomen and massive hemoperitoneum. The diagnosis was initially suspected peroperatively and subsequently confirmed by histopathological examination of the surgical specimen. Postoperative management and surveillance were conducted through serial quantitative plasma beta-human chorionic gonadotropin (β-hCG) monitoring to ensure complete resolution and screen for persistent gestational trophoblastic neoplasia. Although tubal molar pregnancies are rare and potentially life-threatening due to the risk of hemorrhage, they are associated with an excellent prognosis and high cure rates when managed with timely surgical intervention and specialized follow-up. This case underscores the importance of considering molar etiology in ectopic presentations and the necessity of systematic pathological analysis of all products of conception.
