ABSTRACT: A diagnosis of mixed testicular neoplasia in a short beaked common dolphin Delphinus delphis involving a Sertoli cell tumor, an interstitial (Leydig) cell tumor and a seminoma is presented. Lymphatic spread of the Sertoli cell tumor to an adjacent retroperitoneal lymph node was observed. Testicular neoplasms have been infrequently reported in marine mammals. Demonstration of clinical signs and further health implications is extremely challenging when dealing with non accessible wildlife species, such as dolphins. However, metastatic potential for these neoplastic conditions should be considered.
