Teratoma imaturo de ovário bilateral com metástase peritoneal, em gestante de 18 anos: da biópsia ao pós-parto

Abstract

Malignant germ cell tumors account for less than 5% of all ovarian cancers, and immature teratomas account for 35,6% of these tumors. They are characterized by large volumes and rapid growth, with unilateral occurrence, sometimes associated with contralateral benign cystic teratomas. Treatment is surgical, with combination of chemotherapy according to clinical staging, which can be performed in the second and third trimesters of pregnancy, with safety for the fetus and a positive impact on maternal outcome. This study aims to describe an uncommon case of immature ovarian teratoma, with rare bilateral involvement, diagnosed in a pregnant woman monitored by the HUPES oncogynecology team. The patient underwent right oophorectomy at 14 weeks and 3 days of gestation. The pregnancy was terminated at 32 weeks and 2 days due to clinical complications resulting from disease progression, for immediate initiation of chemotherapy. Six cycles of BEP were performed, with hematologic and infectious complications that led to death.
