Abstract

A 3-year-old, pregnant, Alpine Brown cow showed a rapidly growing, pedunculated, skin mass located at the umbilical region, reaching 8 kg in weight over a 3-month period after its initial detection. Six days after parturition, the mass was completely surgically excised. During the follow-up period, the cow remained in good health, without signs of recurrence, and showed increased milk production. Histological examination of the mass revealed a loose proliferation of spindle-shaped or stellate cells, immersed in an abundant myxoid matrix with admixed numerous thin-walled blood vessels. Immunohistochemically, the tumour cells were positive for vimentin, α-smooth muscle actin, and desmin. Gross and histopathological features were compatible with superficial angiomyxoma, a subtype of angiomyxoma rarely described in humans, but not in the veterinary literature. The tumour did not infiltrate into the surrounding tissues, and there was no post-excision recurrence after 3 months. The possibility of hormonal dependence of the tumour during pregnancy is discussed based on such findings in some human cases.

怀孕母牛的浅表血管粘液瘤。
一头3岁的怀孕的阿尔卑斯棕色奶牛在脐部出现了一个快速生长的、带梗的皮肤肿块,在最初发现后的3个月内体重达到了8公斤。分娩后6天,肿块被手术完全切除。在随访期间,奶牛健康状况良好,无复发迹象,产奶量增加。组织学检查显示梭形或星状细胞松散增生,浸润在丰富的黏液基质中,混杂着大量薄壁血管。免疫组化结果显示,肿瘤细胞波形蛋白、α-平滑肌肌动蛋白、desmin阳性。大体和组织病理学特征与浅表血管粘液瘤一致,浅表血管粘液瘤是一种很少在人类中描述的血管粘液瘤亚型,但在兽医文献中没有。肿瘤未浸润周围组织,术后3个月无复发。根据在一些人类病例中的发现,讨论了怀孕期间肿瘤激素依赖性的可能性。
