This document describes the case of a 17-year-old female patient who presented with profuse vaginal bleeding. Her physical examination revealed an enlarged uterus consistent with 18 weeks gestation and a non-dilated cervix. She was diagnosed with a hydatidiform mole based on her symptoms of metrorrhagia and abdominal mass without pressure signs, as well as ultrasound findings. She underwent dilation and suction curettage for management of the molar pregnancy, and will require follow-up hCG monitoring to check for any persistent gestational trophoblastic disease.
