A case of teratoma in a male patient aged 53 years old at the liver left lobe, hospitalized 25 November 2002 at The Hospital 198 was persented. It was a special form of mature teratoma of dermoid cyst. Macroscopically, it was a cyst of large size with thick fibroid shell, containing fat fluid, caseinous matter, hair, cartilaginous bone and even 3 molar teeth. Microscopically, it was a lining of cells of keratinoid epithelial scale tissue in the wall. Under the epithelial cover there was a conjunctive tissue inserted by sebacenous tissues, sweat gland tissues, hair alveoli and vessels with thick fibrous wall.

We report a case of immature teratoma arising at the suprasellar region in a 18 year-old-male who presented with bitemporal hemianopsia, nausea and polydipsia. The teratoma is a rare neoplasm consisting of 0.5% to 1.2% of all intracranial tumors. The clinical presentation, radiologic finding, pathology and treatment are briefly described with a review of other cases from the literature in view of clinical features and management.

The benign teratoma is usually slow growing tumor, but we expirienced a case of primary huge mediastinal benign teratoma that had grown very rapidly, maximally during 3 years. The 14-year-old female patient was admitted to our hospital because of abnormal chest X-ray that showed 10x10cm sized well definded mass with multiple calcificactions. but the mass was not present in chest X-ray perfomed on 3 years prior to admission. Under the diagnosis of teratoma, complete surgical resection was done by the left thoracotomy. The result of pathology was benign teratoma.

Two case of primary intracranial teratomas are presented. One case is right cerebellopontine angle malignant teratoma of 3years old female and the other case is left frontal benign teratoma of 40 years old male. We reviewed the literatures and discussed these cases in the point of the rare sites and pathological characteristic of teratoma.

Dermoid cysts in floor of mouth are relatively rare. The term dermoid cyst is used to describe 3 cysts that are closely related histologically: dermoid cyst, epidermoid cyst, and teratoma. These are frequently mistaken as other pathology because of their location and rarity. Complete surgical excision is the treatment of choice and the recurrence is extremely rare. We report each case of epidermoid cyst and dermoid cyst of the floor of the mouth with a brief review of literatures.

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 teratoma was grade II, the patient received adjuvant chemotherapy. The patient died of progression of the intra-abdominal tumor 6 months after surgical excision. The authors believe this to be the first presentation in the world literature.
