Congenital endodermal sinus tumor of the penis

Journal of Pediatric Surgery, 1987
Congenitally occurring endodermal sinus tumors are very rare and frequently occur in association with teratomatous growths. The most common location for these tumors in infancy is the gonads. Tumors of the penis are rare in any age group. As far as we know, this tumor has never been reported in the penis.

Retroperitoneal Endodermal Sinus Tumor

2017
Germ cell tumors can be divided into seminomas and non-seminomatous tumors, which include embryonal carcinomas, endodermal sinus tumors, choriocarcinomas, teratomas, and mixed germ cell tumors. The vast majority originates in ovary and testis gonads, and a small number occurs beyond gonads. Retroperitoneum is the second most common site of extragonadal

Endodermal Sinus Tumor of the Mediastinum

Chest, 1977
This is the eighth case report of an endodermal sinus tumor of the mediastinum (first case studied by electron microscopy). The ultrastructure of the tumor was found to mimic that of the normal yolk sac and was also similar to that of three previously reported cases of endodermal sinus tumor of the ovary, thus confirming the correctness of Teilum's ...

Endodermal sinus tumors in the head and neck region

Medical and Pediatric Oncology, 1997
Extragonadal germ cell tumors of the head and neck region account for only 5% of all benign and malignant germ cell tumors. Endodermal sinus tumors (EST) of the head and neck region are rare. We report three patients with EST of head and neck region over a period of 10 years; the primary sites of tumor were orbit, maxillofacial region and ...

A study on alpha-fetoprotein and endodermal sinus tumor

Journal of Pediatric Surgery, 1975
Abstract The phenomenon of alpha-fetoprotein production by testicular, ovarian, or sacrococcygeal teratocarcinomas is frequently observed but has not been well explained. This paper includes clinicopathologic studies of 19 cases of teratocarcinoma with positive AFP reactions.

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 ...

Endodermal sinus tumor or orchioblastoma in children and adults

Virchows Archiv A Pathological Anatomy and Histology, 1974
19 “endodermal sinus tumors” of infantile testes and 5 analogous testicular tumors in adults were studied. The histopathology and prognosis of these cases are shown. As Teilum postulated, the “endodermal sinus tumor” should be a unilaterally developed teratoma mimicking embryonal yolk sac tissue.

Endodermal Sinus Tumor of the Parotid Gland in a Child

Pediatric and Developmental Pathology, 2004
We report a case of a 16-month-old girl with a primary endodermal sinus tumor (EST) of the parotid gland. The girl was admitted to the hospital with a left side cervical tumor with a quick growth (within 3 wk). The tumor was surgically resected. The gross examination showed a 7.0-cm hemorrhagic and fragmentized mass.

An endodermal sinus tumor of the head and neck region

International Journal of Pediatric Otorhinolaryngology, 1993
A 2-year-old patient with a recurrent endodermal sinus tumor of the nasopharynx is presented. After the first attempt to surgically excise the tumor it recurred, causing upper airway obstruction within 2 months. Combined treatment with surgery, radiotherapy and chemotherapy resulted in a disease-free survival of four years.
