Teratoma sacrococcígeo gigante, distocia y preeclampsia. Análisis de un caso clínico y posmortem

Abstract

Sacrococcygeal teratoma is the primary extragonadal germ cell neoplasm in childhood. This tumor is usually detected in the neonatal period and may become malignant. Treatment is surgical. The incidence of this entity is low and diagnosis can be made in utero. However, prognosis is given by histopathologic correlation only. The perinatal importance of this entity lies in its size, which causes high fetal and perinatal mortality and complications such as dystocia, polyhydramnios, preterm labor, rupture of the tumor and preeclampsia.There is a risk of malignant transformation in 5% of mature teratomas. The treatment of choice is complete tumor resection and surveillance of tumoral markers is indispensable. We report a case of giant sacrococcygeal teratoma and discuss the postmortem analysis and perinatal implications.
