Human Germ Cell Tumors are Developmental Cancers: Impact of Epigenetics on Pathobiology and Clinic
International Journal of Molecular Sciences, 2019 Current (high throughput omics-based) data support the model that human (malignant) germ cell tumors are not initiated by somatic mutations, but, instead through a defined locked epigenetic status, representative of their cell of origin.

Primary Germ Cell Tumors of the Mediastinum: 10 Years of Experience in a Tertiary Teaching Hospital
Kaohsiung Journal of Medical Sciences, 2005 Germ cell tumors occur mostly in the gonad. Extragonadal germ cell tumors are rare, and most occur in the retroperitoneum and mediastinum. Primary mediastinal germ cell tumors are often found in the anterior portion of the mediastinum and include ...

Extragonadal germ cell tumor, a report of two cases presenting in the gastrointestinal tract
Rare Tumors, 2021 Germ cell tumors are a heterogeneous group of tumors that can present primarily as gonadal tumors in either a localized or metastatic pattern. Rarely these tumors can initially present at extra-gonadal locations, including the gastrointestinal tract.

Pediatric Germ Cell Tumors: A Developmental Perspective
Advances in Urology, 2018 Germ cell tumors (GCTs) arising in infants, children, and adolescents present a set of special challenges. GCTs make up about 3% of malignancies in children aged 0–18 and nearly 15% of cancers in adolescents. Epidemiologic and molecular evidence suggests

On the Origin of Testicular Germ Cell Tumors: From Gonocytes to Testicular Cancer
Frontiers in Endocrinology, 2019 Human primordial germ cells (PGCs) have been described in the yolk sac wall around the beginning of the third week. From week 4 to 5, they migrate under control of SCF/c-KIT signaling pathway to the genital ridge, where they become gonocytes.

A Rare Case of Primary Anterior Mediastinal Yolk Sac Tumor in an Elderly Adult Male
Case Reports in Oncological Medicine, 2016 Mediastinal germ cell tumors are extragonadal germ cell tumors (EGGCTs) commonly seen in children and young adults. They are more common in men. Clinically they are classified as teratomas, seminomas, and nonseminomatous germ cell tumors.

Mixed germ cell tumors: Report of two cases
Medical Journal of Dr. D.Y. Patil University, 2013 Germ cell tumors arise in the ovaries and testis and rarely in other tissues. Mixed germ cell tumors are rare. We report two cases of mixed germ cell tumors, one consisting of seminoma and immature teratoma in the testis of a 30-year-old male and second ...
