BACKGROUND Mature sacrococcygeal teratomas (SCT) are uncommon neoplasms comprised of mixed elements derived from the three germ cell layers. They attract attention because of their gross appearance and bizarre histology. AIM To demonstrate the clinical presentation and management of mature SCT in a neonate. PATIENT AND METHOD A case report of a neonate with mature SCT is hereby presented. ...

This report describes a case of sacrococcygeal teratoma with adenocarcinomatous transformation in a 45-year-old woman. This is an infrequent location for teratoma in adults and malignant transformation has rarely been described. Prognosis depends on complete excision. Clinical manifestations, imaging aspects and histological findings of this case are presented. CT and MRI adequately document th...

Tumors of neuroepithelial origin are extremely rare in teratoma and tend to be derived from glial or primitive neuroectodermal cells. We describe a case of 2- month-old baby girl with an oligodendroglioma arising in an immature teratoma of the sacrococcygeal region. Histologically, the tumor was identical in appearance to low grade oligodendroglioma within the adult brain. Because immature tera...

Although the sacrococcygeal area is the most common site for a teratoma in infants, it is a rare site for a teratoma in older patients. Most of the teratomas found in this area in adults are single mass, but in a few cases, multiple masses have been reported. The author reports on the case of an 18-year-old female patient with 3 presacral teratomas. The tumors were surgically removed via a tran...

Two-thirds of all teratomas seen in 31 Nigerian children at Ibadan were situated in the sacrococcygeal region. About one-quarter of all the sacrococcygeal teratomas were malignant as shown on radiological and pathological examinations. The m...
