Gestational trophobalstic neoplasia encompasses invasive mole, placental site trophoblastic tumor, epitheloid trophoblastic tumor and choriocarcinoma. Here we report a 27 year old woman with invasive mole with severe anaemia who was initially misdiagnosed as a case of incomplete abortion with vascular malfomarmation of uterus. In view of uncontrolled bleeding per vaginum, nonspecific ultrasound findings and H/O failed dilatation and evacuation, exploratory laparotomy was decided upon and intraoperative finding was invasive mole. Hysterectomy was done.
