It is the most common tumor of newborns, although it is quite rare occurring in approximately 1 in every 40,000 births. The sacrococcygeal region is the most common site for a teratoma in infants. Teratomas are congenital or developmental tumors which are derived from multi-potent cells and differentiate into diverse types of tissue, representative of all three germ layers ().Teratomas are rare tumors, accounting for only 3% of all childhood tumors, with sacrococcygeal teratoma being the most common (57%) followed by gonadal teratoma (29%).

SCTs are categorized according to the classification developed by the American Academy of Pediatrics, Surgical Section (AAPSS), as follows [ 12] : Type I - Primarily external or has a minimal. SCTs are relatively rare and occur in approximately 1 out of every 23,000 to approximately 1 out every 40,000 pregnancies worldwide. In adults, the most common sites are the anterior mediastinum, retroperitoneum, and the pineal and suprasellar regions. This resection in stage I tumors can be made exclusively by perineal incision while a combined abdominal and perineal approach may be necessary for other types [2,3,6].

It is typically diagnosed prenatally (before birth), or in some cases, shortly thereafter. Diagnosis mainly relies on clinical examination and imaging.

Keywords: Adult; Sacrococcygeal; Teratoma Introduction Teratomas are germ cell tumors composed of multiple cell types which originate from one or more of the 3 germ cell layers. Audet IM(1), Goldhahn RT Jr, Dent TL. 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. In most cases, treatment of sacrococcygeal teratoma is surgery shortly after birth to remove the tumor (and the coccyx, to prevent recurrence). Although the tumors can grow very large, they are usually not malignant (that is, cancerous). A sacrococcygeal teratoma (SCT) is a germ cell tumor that is located close to the sacrum and coccyx. Open fetal surgery has been used in select babies with a sacrococcygeal teratoma with high blood flow and heart failure before 30 weeks gestation. Indeed, teratomas have been reported in twins, in nontwin siblings, in triplets, in a mother and her two adult daughters, and in three generations. The majority of teratomas are located in the gonads and sacrococcygeal area, but may also be found in the mediastinum and retroperitoneum [4, 12, 13].In an adult, the present complaint in most instances is that of a mass, frequently located at the base of the spine or .

The treatment of sacrococcygeal tumors is mainly surgical and consists of resection of the tumor with the coccyx [1-9]. Mediastinal mature teratomas are benign neoplasms that usually arise in or near the thymus and account for 70-75% of primary germ cell tumors of the mediastinum 2, 3. We report a rare case of a benign adult sacrococcygeal teratoma discovered during pregnancy. Early surgical excision of the mass will reduce the potential for malignant transformation as well as the risk of recurrence.

Adults cases often represent tumors that were present at birth (congenital), but not detected until adulthood. The baby remains on placental support while the bulk of the tumor is removed. Sacrococcygeal teratomas are the most common solid tumor in newborn infants. A number of tumors are known to involve the coccyx; of these, the most common is sacrococcygeal teratoma. The cystic lumen mainly contains sebaceous materials and hairs.

Sacrococcygeal teratoma is one of the most common tumours in infants but rare in adults. This birth defect is more common in girls than in males. The sacrococcygeal area is the most frequent site of teratoma in infancy, occurring in 1 of 35,000-40,000 births. The diagnosis is frequently made prenatally, although a delayed presentation, which adversely impacts prognosis, can be seen in patients with intra-abdominal lesions. The tumor is located at the base of the tailbone, called the coccyx. This report describes a case of sacrococcygeal teratoma, a rare pathology belonging to the group of presacral tumors. Sacrococcygeal teratoma is an infrequently encountered tumor. Since the prognosis for malignant cases is poor, prompt surgical resection is required [ 3 ]. Although the tumors can grow very large, they are usually not malignant (cancerous). Saudi Med J 2004;25:367-9. However, in cases involving large tumors or tumors demanding high blood flow, life-threatening complications can occur during pregnancy that require fetal intervention.
