A Metastatic Invasive Mole in a Perimenopausal Woman: A Rare Case

Gestational trophoblastic neoplasia (GTN) represents a heterogeneous group of pregnancy-related tumors that usually develop from the malignant transformation of trophoblastic tissue after molar evacuation. The first presentation as an invasive mole is particularly rare. GTN is considered the most curable gynecological malignancy as most cases are treated successfully with chemotherapy agents. Although extremes of reproductive age are an established risk factor for complete moles, GTN is extremely rare in perimenopausal women. GTN should be considered in the differential diagnosis of patients with abnormal uterine bleeding. Delays in the diagnosis and treatment can worsen the prognosis of patients with GTN.Here, we describe the case of a 54-year-old woman who presented to the emergency department with abdominal pain and heavy vaginal bleeding. She reported pregnancy-related symptoms that had developed over two months but was apprehensive to search for medical care. The final diagnosis was an invasive mole that had a catastrophic clinical course. Arterial embolization should be considered in patients with uncontrollable vaginal bleeding and hemodynamic instability.
