Primary testicular neoplasms are common in dogs, but metastases to the testes are rare. Three dogs had enlargement of the testes and associated structures. Upon histological examination, the enlargements were due to metastatic adenocarcinomas. Further examination identified the gastrointestinal tract as the primary site of the metastatic neoplasms in all three cases. The testicular metastases reflected widespread metastatic disease. When metastatic adenocarcinoma is found in the testes and associated structures in dogs, the gastrointestinal tract should be examined closely for a primary tumor site.
原发性睾丸肿瘤在犬类中很常见，但睾丸转移瘤却很罕见。三只犬的睾丸及相关结构出现肿大。经组织学检查，肿大是由转移性腺癌所致。进一步检查发现，在所有三例病例中，胃肠道是转移性肿瘤的原发部位。睾丸转移反映了广泛的转移性疾病。当在犬的睾丸及相关结构中发现转移性腺癌时，应仔细检查胃肠道以寻找原发肿瘤部位。
