摘要

在哺乳动物中，卵巢内发生性腺肿瘤的情况非常罕见，而且在奶牛中也未见报道。我们在此报告了在一头 15 个月大的小母牛卵巢中发现的性腺基质（颗粒细胞）肿瘤，这头小母牛的生殖道是从当地屠宰场获得的。组织病理学评估显示该性腺为卵巢，但同时也发现了性索间质（颗粒细胞）肿瘤。性染色体类型被确定为 XX，这表明该患者患有 XX 型卵巢性发育障碍，并伴有子宫和女性表型。主要临床信息：性发育障碍在哺乳动物中很常见。性发育障碍中的性腺肿瘤很少见，在奶牛中也未见报道。

Sex cord-stromal (granulosa cell) tumor in an ovotestis from a cow.

Development of gonadal tumors within an ovotestis is rare in mammals and this disturbance was not reported in cows. We report herein a gonadal stromal (granulosa cell) tumor in an ovotestis of a 15-month-old heifer from which the reproductive tract was obtained from a local slaughterhouse. Histopathological evaluation revealed that the gonads were ovotestis, but also a coincidental sex cordstromal (granulosa cell) tumor. The sex chromosome type was determined to be XX, suggesting an XX ovotesticular disorder of sexual development with uterus and a female phenotype. Key clinical message: Disorders of sexual development are common in mammals. Gonadal tumors in disorders of sexual development are rarely reported and have not been reported in cows.

期刊介绍： The Canadian Veterinary Journal (CVJ) provides a forum for the discussion of all matters relevant to the veterinary profession. The mission of the Journal is to educate by informing readers of progress in clinical veterinary medicine, clinical veterinary research, and related fields of endeavor. The key objective of The CVJ is to promote the art and science of veterinary medicine and the betterment of animal health. A report suggesting that animals have been unnecessarily subjected to adverse, stressful, or harsh conditions or treatments will not be processed for publication. Experimental studies using animals will only be considered for publication if the studies have been approved by an institutional animal care committee, or equivalent, and the guidelines of the Canadian Council on Animal Care, or equivalent, have been followed by the author(s).
