Abstract:
UNASSIGNED: A 5-year-old female neutered Siberian Forest Cat presented with a 7-day history of lethargy, hyporexia and weight loss. Abdominal ultrasonography revealed bilateral renal changes suggestive of neoplasia. Thoracic radiography documented diffuse pulmonary nodules. The cat was euthanased during diagnostic investigations. Histopathological assessment and immunohistochemical staining of post-mortem renal biopsies were consistent with a histiocytic lesion, most likely histiocytic sarcoma (HS). The lung lesions were suspected of representing disseminated disease.
UNASSIGNED: HS is considered a rare neoplastic process in cats. This report describes a case of feline bilateral renal HS with suspected concomitant pulmonary involvement. A primary renal origin was suspected, with the lung lesions being a result of disseminated disease. Renal HS should be included as a differential diagnosis when renal ultrasonography reveals changes suggestive of neoplasia.
摘要:
■一只5岁雌性绝育的西伯利亚森林猫,有7天的嗜睡史,缺氧和体重减轻。腹部超声检查显示双侧肾脏改变提示瘤形成。胸部X线摄影记录弥漫性肺结节。该猫在诊断调查期间被安乐死。死后肾活检的组织病理学评估和免疫组织化学染色与组织细胞病变一致,最可能是组织细胞肉瘤(HS)。怀疑肺部病变代表播散性疾病。
■HS被认为是猫中罕见的肿瘤形成过程。本报告描述了一例猫科动物双侧肾脏HS,怀疑伴有肺部受累。怀疑是原发性肾脏起源,肺部病变是传播疾病的结果。当肾脏超声检查显示提示瘤形成的变化时,应将肾脏HS作为鉴别诊断。
