Abstract
BACKGROUND: Ectopic molar pregnancy (EMP) is a rare form of gestational trophoblastic disease that occurs when a hydatidiform mole implants outside the uterus. CASE PRESENTATION: We describe a 35-yr-old woman with mild abdominal pain, delayed menstruation for 2 months, and high beta-human chorionic gonadotropin levels. Sonography revealed a heterogeneous hyperechoic mass in the left adnexa and fluid in the endometrial cavity, suggestive of a tubal EMP. She underwent endometrial curettage and left salpingectomy. Pathology confirmed the diagnosis of invasive hydatidiform mole/left tubal EMP. The case recovered well and had no complications. CONCLUSION: This case highlights the need for early diagnosis and multidisciplinary treatment of EMP to avoid serious consequences from persistent trophoblastic tumors.
