The photograph shows the cut surface of a testis tumor. The tumor is fleshy and replaces the testis. The cut surface is fairly homogenous in character, with only a limited area of hemorrhage and necrosis. The attached elongate structure is the spermatic cord.
Seminomas are germ cell neoplasms.
Peak incidence in the fourth decade of life. On cut section, the tumor is usually gray-white, homogenous and lobular. Necrosis and hemorrhage are inconspicuous in small tumors and more notable in larger tumors. Typical seminoma is composed of monotonous sheets of uniform round cells with rather clear cytoplasm and centrally located round nuclei with prominent nucleoli. Seminoma occur most frequently in the fourth and fifth decade of life.
