Bilateral seminoma in a duck (Anas platyrhynchos).
A case of bilateral seminoma in an aged Mallard duck (Anas platyrhynchos) is described. Both testes were enlarged. Historically, the testes revealed large irregular seminiferous tubules containing diffuse sheets of large round, hyperchromatic neoplastic spermatogenic cells. Mitotic figures were seen. The growth had spread diffusely in both testes with no normal tissue left. Occurrence of bilateral seminoma without metastasis to other organs is unusual.
