The authors present a case report of a pregnant woman with persistent left adnexal mass and subsequently found to have a primary endodermal sinus tumor of the ovary that was diagnosed at 19 weeks of gestation. After left salpingooophorectomy had been performed, the patient chose to terminate the pregnancy before the initiation of combination chemotherapy with bleomycin, etoposide, and cisplatin. The response to chemotherapy was not satisfactory. The patient expired after seven cycles of treatment had been completed because of pulmonary fibrosis and the drug toxicity of bleomycin.Mahidol UniversityMedicineArticleSCOPUS
