A 17-year-old Quarter Horse mare was examined nearly 3 years after excision and cryotherapy of a papillary mammary gland adenocarcinoma. The mare had been used for pleasure riding since surgery, but had recently developed progressive dyspnea. The mare had clinical evidence of pleural effusion, but died before further clinical examination and treatment were instituted. Necropsy revealed deep mammary masses with similar nodules in the deep inguinal, renal, and mediastinal lymph nodes and in the lungs, pericardium, visceral and parietal pleurae, and left ovary. The masses were identified as papillary mammary gland adenocarcinoma. Large volumes of free pleural and peritoneal fluid were detected. The pleural fluid contained similar neoplastic cells that could have been readily detected by exfoliative cytologic examination had the mare survived.
一匹17岁的夸特马母马在乳头状乳腺腺癌切除及冷冻治疗近3年后接受检查。自手术以来，这匹母马一直用于休闲骑行，但最近出现了进行性呼吸困难。该母马有胸腔积液的临床证据，但在进一步的临床检查和治疗开始前死亡。尸检发现乳腺深部有肿块，腹股沟深部、肾、纵隔淋巴结以及肺、心包、脏层和壁层胸膜及左卵巢有类似结节。这些肿块被确诊为乳头状乳腺腺癌。检测到大量游离的胸腔和腹腔积液。如果这匹母马存活下来，胸腔积液中含有的类似肿瘤细胞本可通过脱落细胞学检查轻易检测到。
