Immature teratoma of the ovary

Gynecologic Oncology, 1991
The purpose of this study was to establish the optimal management of immature teratoma of the ovary. Pursuant to this, 20 previously untreated patients with immature teratoma were evaluated. Nine patients were at stage I of the disease, 2 had progressed to stage II, and 9 to stage III. Eight patients had grade 1 tumors, 11 had grade 2 tumors, and 1 had

Immature teratoma of the ovary

Gynecologic Oncology, 1988
Results of treatment of 9 cases of pure immature teratoma of the ovary seen at the University Hospital, Kuala Lumpur, are presented. Six patients were in Stage 1 and three in Stage 3. A majority of them had grade 2 or 3 tumors. Four patients in Stage 1 had the conservative surgery of salpingo-oophorectomy performed, the more radical procedure of total ...

Giant immature teratoma

The Spine Journal, 2015
We managed a case of a spinal immature teratoma in a 3-year-old child. Magnetic resonance imaging revealed an expansive mass in the sacrococcygeal and lumbar regions (Figs. 1 and 2). The mass was hyperintense on T2-weighted (T2W) and hyperintense–hypointense on T1-weighted (T1W) images (Figs. 1 and 2).

Immature teratoma of the ovary

International Journal of Gynecology & Obstetrics, 1989
Twenty-five cases of patients with pure immature teratoma of the ovary, accrued from the Connecticut Tumor Registry from 1969 to 1984, were reviewed. Two patients had grade 1 tumors, twelve had grade 2 tumors, and eleven had grade 3 tumors. The majority of patients (23) were stage I at the time of initial surgery.

Immature teratoma of the ovary

American Journal of Obstetrics and Gynecology, 1983
Four cases of immature teratoma of the ovary are presented and the recent literature is reviewed. The majority of these tumors were confined to one ovary at the time of diagnosis, and more than 75% occurred in women under 25 years of age. The two most important prognostic parameters were stage of disease and histologic grade.

Origin of immature teratoma of the ovary

American Journal of Obstetrics and Gynecology, 1985
Six cases of immature teratoma of the ovary were karyotyped and analyzed for chromosomal heteromorphisms, enzyme polymorphisms, and HLA specificities to determine their mechanism of origin. Three cases were chromosomally abnormal, with karyotypes of 48,XX, +14, +21; 47,XX, +20; and 47,XXX, respectively.

Massive immature teratoma in a neonate

International Journal of Oral and Maxillofacial Surgery, 2010
Teratomas are embryonal tumours composed of diverse tissues from three germinal layers with variable levels of maturity. The authors report a female patient with a large immature epignathus. Prenatal diagnosis permitted a caesarean section and tracheotomy to be planned under ex utero intrapartum treatment for airway obstruction.

Immature teratomas in children

Histopathology, 1988
In a retrospective study comprising 216 germ‐cell tumours occurring in children from birth to the age of 18 years, 27 immature teratomas were found at a variety of sites. Seventeen of these were curatively treated by means of one operation. Only two patients died as a direct result of tumour growth.
