Gestational trophoblastic tumor in pregnancy: a case report and review of the literature.

A case of gestational trophoblastic tumor (GTT) concurrent with an intrauterine pregnancy is reported in a 21-year-old gravida 2 para 0 (0010) who presented with dyspnea, orthopnea, headache, and blurring of vision at 33 weeks age of gestation. She had a history of hydatidiform mole for which curettage was done. Chest radiograph showed pulmonary metastases, with pleural effusion on both lungs. Serum beta subunit of human chorionic gonadotropin was abnormally elevated for age of gestation. Due to worsening maternal pulmonary condition, the patient underwent primary, low segment cesarean section and was subsequently started on multidrug chemotherapy. This is the first reported case of GTT in pregnancy in the Philippines in which both the mother and the infant survived. Several hypotheses regarding its origin, its diagnosis, and its management and prognosis are presented. This case report emphasizes the importance of early diagnosis and treatment to improve the prognosis of both the mother and the infant.
