Identification of ERβ1 and ERβ2 in human seminoma, in embryonal carcinoma and in their adjacent intratubular germ cell neoplasia [PDF]

Reproductive Biology and Endocrinology, 2009
Background Estrogens exert a role on germ cell physiology of normal human testis through the mediation of the estrogen receptor (ER) beta subtypes. Epidemiological studies evidenced an increased incidence of testicular germ cell cancer after elevated pre-

Testicular Embryonal Carcinoma With Retroperitoneal Metastasis and Normal AFP and HCG: A Case Report [PDF]

Case Reports in Oncological Medicine
Testicular germ cell tumors are common malignant tumors in young men, among which embryonal carcinoma, as an important subtype of non-seminomatous germ cell tumors, is usually accompanied by elevated serum tumor markers.

Diagnosis, treatment, and long-term follow-up of a 13-year-old boy with a testicular mixed germ cell tumor (yolk sac tumor and embryonal carcinoma): a case report and literature review [PDF]

Frontiers in Pediatrics
Testicular germ cell tumors (TGCTs) are rare in children under 15 years of age. We report the first documented case of a mixed yolk sac tumor and embryonal carcinoma in the left testis of a 13-year-old boy in the early stages of puberty (12–14 years ...

Giant Mediastinal Germ Cell Tumour: An Enigma of Surgical Consideration [PDF]

Case Reports in Surgery, 2016
We present a case of 16-year-old male, who was referred from private centre for dyspnoea, fatigue, and orthopnea. The chest radiograph revealed complete opacification of left chest which was confirmed by computed tomography as a large left mediastinal ...

A rare case of pure-type embryonal carcinoma in a 75-year-old woman mimicking epithelial ovarian carcinoma [PDF]

Kosin Medical Journal, 2022
Embryonal carcinoma, a very rare ovarian germ cell tumor, involves pure and mixed phenotypes. Pure-type embryonal carcinoma has never been reported in postmenopausal women. The current case was, thus, misdiagnosed as an epithelial ovarian carcinoma based

Specifying Mouse Embryonic Germ Cells [PDF]

Cell, 2009
Male germ cells are induced to form from the epiblast of the mouse embryo by a combination of WNT and bone morphogenetic protein signals. Ohinata et al. (2009) now clarify the steps of mouse germ cell formation and use this genetic insight to direct the specification and differentiation of germline progenitor cells in vitro.
