Gestational trophoblastic neoplasia (GTN), a malignancy arising from trophoblastic tissue of pregnancy, is an aggressive disease process with a high probability of metastasis if left untreated. This is a case report on metastatic invasive mole arising from a molar pregnancy. Four months after suction curettage, a mass was noted in the left broad ligament on exploratory laparotomy with intact uterine serosa. Clinical presentation, biochemical, and radiological parameters led to a diagnosis of persistent trophoblastic disease. Histopathological findings also confirmed the diagnosis. Prompt chemotherapy was given after removal of the left intraligamentary mass, and subsequent response to treatment was documented. We report a case demonstrating a different clinical presentation of invasive mole and its potential to metastasize to the broad ligament without uterine perforation or direct extension.
