Right-sided orchidectomy is performed. Grossly, the mass measures 5x4x3 cms and the cut surface has a soft gelatinous appearance. Microscopically, it is composed of cells with perfectly round nuclei and prominent variation in size. Bizarre giant forms, as well as small cells with a lymphocyte-like appearances are seen. Numerous mitoses are observed. There are no areas of lymphocytic infiltration. The patient is perfectly normal even 5 years following surgery. What is the BEST diagnosis in this case?
