Spermatocytic Seminoma

slide 88 of 114

Comments:
The patient, a 71 y/o male, was found to have a right testicular nodule on routine examination. Ultrasound showed a hypervascular solid mass consistent with a testicular tumor. Serum tumor markers (AFP, beta-hCG, LDH) were within reference range. The tumor measured 4.5 cm and was confined to the testis on gross examination. It had multiple fleshy nodules, white areas, mucoid foci and areas of hemorrhage. Spermatocytic seminoma occurs only in the testis and is not associated with intratubular germ cell neoplasia, cryptorchidism, or other germ cell tumors. For reasons unknown, it occurs more commonly on the right side. Almost 10% cases are bilateral.
