Teratoma gigante sacro-coccígeo: tratamiento quirúrgico. Presentación de un caso Giant sacro-coccygeal teratoma: surgical treatment. A case presentation

Sacro-coccygeal teratoma is a tumor with global incidence of 1 in 35,000 to 40,000 births. It is limited to the coccyx, with possibility of extension to the pelvic/abdominal cavity and external extension development. W e present the case of a male neonate with prenatal diagnosis of a sacro-coccygeal tumor carried out by ultrasound; therefore pregnancy was interrupted by elective caesarean section. We performed the dissection and tumor resection, including the coccyx. We reconstructed the defect with local fl aps with exteriorization of the anal sphincter through the fl ap. The pathology report was malignant teratoma. Despite having achieved good functional and cosmetic results, the patient died within 30 days of extra uterine life by a hospital-acquired complication: sepsis secondary to pneumonia. Teratomas are resected to prevent ulceration, bleeding and reduce the risk of malignancy. Tailbone should be resected to prevent recurrence. The complete excision of benign tumors is enough to cure; malignant teratoma requires chemotherapy adjuvant, which achieves a 60-90% 5-year survival.
