International Urology and Nephrology, 1981
The authors present a case of benign retroperitoneal teratoma in a 3-year-old boy, involving left-sided hydronephrosis. Urography demonstrated that the tumour (as seen in the review photograph) displaced the left kidney and induced considerable hydronephrosis.

A case of placental teratoma is presented. This is a rare tumor of disputed histogenesis. Some regard it as a separate entity while others believe it represents the extreme of a fetus amorphus. The tumor is benign and of no clinical significance.

Journal of Paediatrics and Child Health, 1985
Abstract Eight cases of sacrococcygeal teratoma are described. Seven patients were diagnosed at birth, and one presented at 3 1/2 months of age with urinary retention. Two patients had associated congenital anomalies (arachnoid cyst, external angular dermoid and bifid sacrum), while one had a family history of sacrococcygeal teratoma.

Teratomas are composed of multiple tissues foreign to the organ or site in which they arise. Their origin is postulated by 3 theories one of which is the origin from totipotent primodial germ cells. Anatomically, teratomas are divided into gonadal or extragonadal lesions and histologically they are classified as mature or immature tumors. Teratomas are

Urology, 1978
Two cases of sacrococcygeal teratomas are presented. One case illustrates the long course of urologic problems produced by a "successful" removal of the tumor. The literature is reviewed, and the characteristics of this congenital tumor are discussed.

Oronasopharyngeal teratomas are rare tumours that usually present in the neonatal period with airway obstruction. Management should include prompt establishment of the airway and early excision. Complete excision is recommended, which may require more than one operation, but multilating surgery should be avoided as the malignant potential of these ...

Gastric teratoma accounts for less than 1% of all teratomas occurring in children, usually males. These tumors may be benign or malignant and complete excision of the tumor in either case carries a good prognosis. This rare case is an addition to the few cases of gastric teratomas in females reported in world literature and presenting as an exophytic &

Teratomas excluding monodermal teratomas
Current Diagnostic Pathology, 1995Although only 3% of ovarian teratomas are immature, they account for almost 20% of primitive germ cell tumours and for 10-20% of ovarian cancer in the first two decades, the age group in which these tumours typically occur.14 There is usually a palpable abdominal or pelvic mass, frequently accompanied by pain.

The rare teratoma of the placenta has been compared to the fetus amorphus, two distinguishing characteristics being the teratoma's lack of structural organization and lack of large vessels entering the tumor. A case of placental teratoma and theories of origin are discussed.

This retrospective study details our experience regarding 72 patients with sacrococcygeal teratoma treated over a period of 17 years. The sex incidence was nearly equal, but there was a high proportion of Altmann type IV tumors. A preliminary colostomy before combined abdominosacral excision of large type III and IV lesions reduced morbidity. Sixty-six
