The 2023 edition of ICD-10-CM Q76.428 became effective on October 1, 2022. EPIDEMIOLOGY Sacrococcygeal teratoma is the most common germ cell tumor of childhood. Overview Sacrococcygeal teratoma is classified into four different categories according to the American academy of pediatrics surgery classification based upon the anatomical location of the tumor. A sacrococcygeal teratoma (SCT) is a germ cell tumor that is located close to the sacrum and coccyx. The aim of this study was to evaluate long-term outcomes of sacrococcygeal germ cell tumors (SC-GCTs) over a 15-year period. Board review style answer #1. Standard postnatal care.

Sacrococcygeal teratomas are benign tumors derived from totipotent embryonic cells of the caudal region [1]. Clinical records and slides were reviewed to confirm the original diagnosis. Most frequently recognized fetal neoplasm Incidence: 1 in 35,000-40,000 live births. Teratomas can be classified as mature tumors (cystic or solid), which contain well-differentiated tissues, or as immature tumors, which contain poorly differentiated tissues consisting primarily of embryonic-appearing neuroglial or neuroepithelial components [1, 2]. Results . All tumors are sent to pathology lab for analysis to determine if they are cancerous or benign.

Pathology was immature with no yolk sac elements in 6 of the 7 cases that had an autopsy. The primary treatment of SCT is an early surgical resection with a complete resection of the coccyx (en bloc" resection), malignant tumors are indicated for adjuvant chemotherapy. The tumors are usually bulky and consist of solid and multilocular cystic areas as seen in this image. A pathology-based classification is as: benign (mature): much more common, comprising ~ 60-70%; malignant (immature) Fifty-seven patients were treated for SC-GCTs with the most common in Altman's classification type I . Teratomas are germ cell tumors commonly composed of multiple cell types derived from one or more of the 3 germ layers. The histopathological slides of excised specimens (presacral tumors) were available for re-examination. Teratoma is a subtype of germ cell tumors (GCT) derived from more than one of the three germinal layers. Clinical presentation Presentation varies depending on if a tumor has an intrapelvic location or has an extra-fetal extension (see further classification below).

This tumor contains derivatives of more than one of the three embryonic germ cell layers and usually arises as a mass in the sacrococcygeal region. The vast majority of sacrococcygeal teratoma's diagnosed in the newborn period are benign. Teratoma. They are postulated to arise from the totipotent somatic cells of the primitive knot [2]. The diagnosis is not difficult in many cases; however, there should be additional information on imaging studies in order to manage those infants properly.

Teratomas range from benign, well-differentiated (mature) cystic lesions. Usually mixed solid and cystic (multiple cysts irregular in shape and size). The tumor is derived from the pluripotential cell line originating in Hensen's node and contains components arising from all three germ layers. This birth defect is more common in female than in male babies. 1 in 20,000 births. SCT arises from aberrant migration of primordial germ cells from the yolk sac to the gonads and accounts for approximately 3% of cancers in children <15 years of age. This finding does not change the prognosis and should not lead to the tumor being classified as immature teratoma. PMID: 25183379; DOI . Congenital lordosis, sacral and sacrococcygeal region.
