The ultrastructure of gonadoblastoma and dysgerminoma

Human Pathology, 1974
Abstract A gonadoblastoma associated with dysgerminoma that occurred in the gonad of a 17 year old phenotypic female has been studied with the electron microscope. Ultrastructurally the nests of gonadoblastoma contain two cell types, namely, large vesicular cells and small epithelium-like cells.

Gonadoblastoma and Turner Syndrome

Journal of Urology, 2006
The presence of a Y chromosome in the extrascrotal gonad of patients with intersex disorders has been associated with a high risk of GB and, potentially, GCT. Recently, modern sophisticated genotyping has revealed a subgroup of TS cases with a mosaic karyotype expressing a Y chromosome.

Gonadoblastoma and Y-Chromosome Fluorescence

Obstetrical & Gynecological Survey, 1986
In this report we summarize our experience in 4 patients with 45, X/46, XY, one patient with 45, X/47, XYY mosaicism, and one patient with 46, XY karyotype and ambiguous external genitalia. In the 3 patients with a fluorescent Y‐chromosome, the development of one or two gonadoblastomas was found, independent of the age of the patients at the time of ...

Gonadoblastoma with Tubal Pregnancy

American Journal of Clinical Pathology, 1976
A case of unilateral gonadoblastoma in association with a ruptured ectopic tubal pregnancy is presented. The patient had normal menstrual history prior to a missed period followed by abdominal pain and the passage of clots. The surgical specimens, in addition to the ruptured tubal pregnancy, showed nodular foci of typical gonadoblastoma in the right ...

Expression of a candidate gene for the gonadoblastoma locus in gonadoblastoma and testicular seminoma

Cytogenetic and Genome Research, 2000
The gonadoblastoma locus on the Y chromosome (GBY) predisposes the dysgenetic gonads of XY females to develop in situ tumors. It has been mapped to a critical interval on the short arm and adjacent centromeric region on the Y chromosome. Currently there are five functional genes identified on the GBY critical region, thereby providing likely candidates

Swyer syndrome with gonadoblastoma

International Journal of Gynecology & Obstetrics, 1981
AbstractAny patient who has a portion of a Y chromosome present should have gonadal extirpation to avoid the risk of gonadal neoplasia, whether benign or malignant. The following case history is presented to illustrate this risk and to lay aside the misconception that such patients are free from risk in the absence of an adnexal mass.

Gonadoblastoma in Patient with Turner's Syndrome

Journal of Obstetrics and Gynaecology Research, 1996
AbstractA 15‐year‐old phenotypic female referred for the investigation of primary ammenorrhea, was found to have a 45 XO karyotype and an ovarian cyst. She demonstrated some of the features of Turner's syndrome, as well as virilization. On laparotomy, she was found to have bilateral gonadoblastomas. She was treated with total abdominal hysterectomy and

Unilateral gonadoblastoma in a pregnant woman

American Journal of Obstetrics and Gynecology, 1969
T H E G 0 N A D 0 B L A S T 0 M A , a rare gonadal tumor related to the dysgerminoma, was first described as a separate entity by Scully2 in 1953. This tumor is composed of germ cells but has in addition stromal cells of the sex cord type ( Sertoli-granulosa) and of mesenchymal origin ( Leydig-theca).
