CLINICAL, ENDOCRINOLOGICAL AND POSTMORTEM OBSERVATIONS A benign granulosa cell tumor was diagnosed in a 19 month old Holstein heifer. Granulosa cell tumors are the most common of the ovarian tumors in cattle. This animal showed no signs of nymphomania or virilism. The principal clinical signs were anestrus and mammary gland hypertrophy. Diagnosis was made by transrectal exam and later confirmed by post-mortem examination. High levels of estrogen and testosterone were present in the plasma and might explain the clinical signs observed in this heifer. The endocrine changes associated with granulosa cell tumors and possible clinical approaches are briefly discussed.
临床、内分泌及尸检观察 在一头19月龄的荷斯坦小母牛中诊断出良性颗粒细胞瘤。颗粒细胞瘤是牛最常见的卵巢肿瘤。这头动物没有表现出慕雄狂或雄性化迹象。主要临床症状为乏情和乳腺肥大。通过直肠检查做出诊断，随后经尸检证实。血浆中存在高水平的雌激素和睾酮，这可能解释了这头小母牛观察到的临床症状。简要讨论了与颗粒细胞瘤相关的内分泌变化及可能的临床处理方法。
