NCI Definition: A malignant germ cell neoplasm arising from the testis. It is composed of primitive epithelial cells arranged in solid, papillary, and glandular configurations. Most patients present with a testicular mass, which may be associated with pain. More than half of the patients have metastatic disease at diagnosis. The form of treatment following radical orchiectomy is stage dependent. [1]

Testicular embryonal carcinomas most frequently harbor alterations in ETV6, CDKN1B, CCND2, RAD52, and KDM5A [2].

Most Commonly Altered Genes in Testicular Embryonal Carcinoma

CDKN1B Amplification, CCND2 Amplification, ETV6 Amplification, RAD52 Amplification, and KDM5A Amplification are the most common alterations in testicular embryonal carcinoma [2].
