Sacrococcygeal teratoma (SCT) is a type of tumor known as a teratoma that develops at the base of the coccyx (tailbone) and is thought to be derived from the primitive streak [citation needed]. Sacrococcygeal teratomas are benign 75% of the time, malignant 12% of the time, and the remainder are considered "immature teratomas" that share benign

Marina N, London WB, Frazier AL, et al. Prognostic factors in children with extragonadal malignant germ cell tumors: a pediatric intergroup study. The prognosis for patients with malignant degeneration is generally poor but dependent on stage and degenerated cell type. Lilly JR. Sacrococcygeal teratoma: American Academy of Pediatrics Background Sacrococcygeal teratomas are tumors originating from pluripotent embryonic germ cell layers located in the fetal coccyx. These tumors are highly vascular if they undergo malignant transformation. Typically, they are found in infants and children and occasionally can be diagnosed prenatally. Adult cases are very rare, and represent tumors present since birth with delayed detection Children with mature teratomas, including mature teratomas of the mediastinum, can be treated with surgery and observation, with an excellent prognosis.[1,10] In a review of 153 children with nontesticular mature teratoma, the 6-year relapse-free survival rate was 96% for completely resected disease and 55% for incompletely resected disease.[ 2 ]

Babies with small tumors that can be removed Researchers know very little about what causes these tumors, but children typically have very positive outcomes after treatment. Between 89 and 96 percent of What is the prognosis of sacrococcygeal teratomas? Sacrococcygeal teratomas are commonly diagnosed prenatally, and complications may occur in utero or 2 Mar 2015 Attempts at defining predictors of poor outcome in fetal sacrococcygeal teratoma ( SCT) have been hampered by small patient numbers. In most cases, treatment of sacrococcygeal teratoma is surgery shortly after birth to remove the tumor (and the coccyx, to prevent recurrence).

In most cases, treatment of sacrococcygeal teratoma is surgery shortly after birth to remove the tumor (and the coccyx, to prevent recurrence). However, in cases The treatment of sacrococcygeal tumors is mainly surgical and consists of resection of the tumor with the coccyx [1-9]. This resection in stage I tumors can be made 7 Feb 2019 unit diagnosed 23 cases of sacrococcygeal teratoma in the period from be normal or increased in sacrococcygeal teratomas and ultrasound.

Prognosis: Perinatal mortality: about 50%, mainly due to the preterm birth (the consequence of polyhydramnios) of a hydropic infant requiring major neonatal surgery. Difficult surgery, especially with tumors that extend into the pelvis and abdomen, can result in nerve injury and incontinence.

Although overall survival is favorable, recurrent tumors are associated with poor outcomes.

In its pure form, mature cystic teratoma of the ovary is always benign, but in approximately 0.2-2% of cases, it may undergo malignant transformation into one of its elements, the majority of which Sacrococcygeal teratomas are commonly considered as lesions at particular risk, in which the coccyx must always be removed together with the mass and overlying skin, taking particular care of the deep pelvic fascia to prevent functional disorders of the bladder and anal canal, as well as any motor alterations of the lower limbs, usually due to iatrogenic lesions of the subfascial nerve structures. The histopathology of 118 sacrococcygeal germ cell tumors (SGCT) was correlated with clinical presentation, therapeutic management, and prognosis. There were 97 teratomas (78 mature, 19 immature), 19 embryonal, and 2 anaplastic carcinomas. Prognosis: Perinatal mortality: about 50%, mainly due to the preterm birth (the consequence of polyhydramnios) of a hydropic infant requiring major neonatal surgery. Difficult surgery, especially with tumors that extend into the pelvis and abdomen, can result in nerve injury and incontinence. Pathology revealed mature, immature, malignant sacrococcygeal teratomas (SCTs), and endodermal sinus tumors (ESTs) in 41 (72%), 4 (77%), 6 (10.5%), and 6 (10.5%), respectively. Recurrence of discase occurred in 3 of 41 patients with mature teratomas (7.3%); 2 recurrences with mature teratomas and one recurrence with EST. None of the factors associated with poor prognosis were independent predictors on multivariate analysis.

We report a case of SCT with hydrops fetalis which was diagnosed antenatally at 30 weeks gestation. Additionally embryological studies and chromosomal analysis of SCTs in large series may be warranted to predict the further prognosis. Key words: Sacrococcygeal Teratoma, Congenital, Histology Prognosis. Most fetuses with sacrococcygeal teratoma do well with surgical treatment after birth. These tumors are generally not malignant.
