Atypical prostatic adenocarcinoma was diagnosed in a castrated dog. The gland was of normal size, contrary to what has been reported in most other cases in dogs. Metastases were not seen, even though radiography suggested metastasis to the external iliac lymph nodes and histologic examination revealed the neoplasm to have a moderately malignant character. Even though hormones have been implicated as a cause of prostatic adenocarcinoma in man, the development of such a neoplasm in dogs castrated at an early age, as exemplified by this case, may cast doubt on that hypothesis.
一只去势犬被诊断出患有非典型前列腺腺癌。与大多数其他犬类病例的报道相反，该腺体大小正常。尽管放射检查提示有髂外淋巴结转移，且组织学检查显示该肿瘤具有中度恶性特征，但未发现转移灶。尽管激素被认为是人类前列腺腺癌的一个病因，但如此例所示，在幼年即被去势的犬类中发生此类肿瘤，可能会使人对该假说产生怀疑。
