Endodermal Sinus Tumor (Yolk Sac Tumor) of the Orbit

Ophthalmology, 1983
The endodermal sinus tumor is a malignant germ cell neoplasm that usually arises in gonads, but on rare occasion occurs in extragonadal locations. Five tumors of the orbit, which by light microscopy displayed features characteristic of gonadal endodermal sinus tumor, were tested for the presence of alpha fetoprotein using paraffin-embedded tissue and ...

Vaginal endodermal sinus tumor

The Indian Journal of Pediatrics, 2005
Malignant germ cell tumors are rare tumors of childhood accounting less than 3% of pediatric malignancies, and endodermal sinus tumor (EST) is the most common histological subtype. The vagina is an extremely rare site for germ cell tumors (GCT). A one-year female was admitted with history of bleeding per vagina.

Endodermal sinus tumor of the clitoris

Gynecologic Oncology, 1980
Abstract A primary endodermal sinus tumor of the clitoris in a 2-year-old is discussed. The serum level of alpha fetoprotein was not elevated. A favorable outcome after exploratory laparotomy and wide local excision might relate to early diagnosis or less virulent patterns of spread secondary to the clitoral location.

Endodermal sinus tumor in children

Journal of Pediatric Surgery, 1996
Malignant germ cell tumors account for about 3% of neoplasms in children, and endodermal sinus tumor (EST) is the most common histological subtype. The authors reviewed 22 years' experience (at their institution) in the management of 37 patients with this tumor.

Endodermal sinus tumor of the mediastinum

Cancer, 1982
Endodermal sinus tumor (EST) of the mediastinum is a rare germ-cell neoplasm affecting mainly young adult males. Ten patients with EST were treated with a multimodality approach that included surgery, chemotherapy, and radiotherapy. All patients had relapses after achieving a transient response except one who is still in complete remission more than ...

ENDODERMAL SINUS TUMOR OF THE STOMACH

Acta Pathologica Japonica, 1985
This is a case report of an endodermal sinus tumor arising in the stomach of a 72‐year‐old Japanese woman. The tumor showed Borrmann 2 type at the mucosal surface, and the main mass occupied the subserosal layer with outgoing extension. Microscopically, the tumor showed typical characteristics of the endodermal sinus tumor, associated with embryonal ...

Endodermal sinus tumor of the vagina

Pediatric Blood & Cancer, 2007
AbstractMalignant germ cell tumors of the vagina represent a critical site for local treatment. We report on our experience with two vaginal endodermal sinus tumors. Treatment with PEB regimen induced both tumor regression and α fetoprotein normalization. One patient had a residual lesion that was biopsed twice and no viable tumor cells were ever found.

Aggressive chemotherapy in endodermal sinus tumor

Journal of Surgical Oncology, 1989
AbstractTwenty‐eight patients with pure or predominantly endodermal sinus tumor were studied for their clinical behavior, relation with serum α‐fetoprotein (AFP), and response to intensive postoperative combination chemother apy. Eight percent of the patients were younger than 20 years of age. One patient was a pseudohermaphrodite.

Endodermal sinus tumor of the ovary in pregnancy

Oncology Reports, 1997
The ultrasonographic evidence of an irregular mixed mass, cystic and solid, in retrouterine area and the high levels of alpha(1)-FP values in a young pregnant woman, indicated the possibility of an ovarian germ cell neoplasia. Respecting the patient's will, pregnancy was protracted until the 36th week.

Endodermal sinus tumor of the vagina and cervix

Cancer, 1985
This report describes six patients with endodermal sinus tumor of the vagina and cervix, a polypoid friable tumor whose clinical presentation in girls younger than age 3 years simulates the presentation of sarcoma botryoides. In four of the six patients, the referring diagnosis was sarcoma botryoides. Five patients were treated with excisional surgery,
