SCT occurs in 1:30,000-40,000 births . During imaging and staging surgery, the findings were strongly suggestive of an extragonadal advanced tumor presenting with peritoneal dissemination, predominantly affecting omentum, with no clear primary origin. Gains in chromosome 12p, including i12p status were assessed in representative paraffin sections by fluorescence in situ hybridization. The . Sacrococcygeal teratoma (SCT) refers to a teratoma arising in the sacrococcygeal region. Sacrococcygeal Teratoma (SCT) is defined as a neoplasm composed of tissues from either all three germ layers or multiple foreign tissues lacking an organ specificity arising in the sacrococcygeal region (Gross et al., 1951; Mahour et al., 1975).

Approximately 75% of affected infants are female [ 1, 2 ]. When these cells develop abnormally, a tumor can result. Sacrococcygeal teratomas are the most common solid tumor in newborn infants. All tumors are sent to pathology lab for analysis to determine if they are cancerous or benign. The aim of this study was to evaluate long-term outcomes of sacrococcygeal germ cell tumors (SC-GCTs) over a 15-year period. In most cases, the SCT is mild, only requiring treatment . Long-term lower gastrointestinal problems (constipation, fecal soiling) correlate with Altman's classification of the tumor, and awareness about this pathology among practitioners is essential and would have avoided complications in this series.

Teratomas are germ cell tumors commonly composed of multiple cell types derived from one or more of the 3 germ layers. Introduction due to abnormal differentiation of fetal germ cells that arise from the fetal yolk sac Teratomas are typically found in the midline or gonads. The sacrococcygeal region is the most common site for a teratoma in infants. Rhabdomyosarcomas are malignant tumors of the primitive mesenchyme that come in 4 sub-types: embryonal, alveolar, botryoid, and pleomorphic. Sacrococcygeal teratomas affecting adults is extremely rare. Teratoma. The diagnosis is not difficult in many cases; however, there should be additional information on imaging studies in order to manage those infants properly.
