Seminoma Testis - Histopathology ; gross ; cross section; microscopic appearance

A seminoma is a germ cell tumor of the testicle or, more rarely, the mediastinum or other extra-gonadal locations. It is a malignant neoplasm and is one of the most treatable and curable cancers, with a survival rate above 95% if discovered in early stages.
Testicular seminoma originates in the germinal epithelium of the seminiferous tubules. About half of germ cell tumors of the testicles are seminomas.Treatment usually requires removal of one testicle. However, fertility usually isn't affected. All other sexual functions will remain intact.
