摘要: 1例3岁雄性家养安德鲁貂,因尾尖有一缓慢生长的肿物而就诊,通过手术完全切除肿物,并对其进行组织病理学检查。结果显示,最后尾椎骨被一个由大的多角形细胞组成的分叶状肿瘤取代,肿瘤细胞的细胞质表现为高度空泡化(physaliferous cells),并可见胞质内PAS(Periodic Acid-Schiff)染色阳性颗粒。免疫组织化学显示细胞质对细胞角蛋白(cytokeratin,CK)和波形蛋白(vimentin)以及中枢神经特异蛋白(S-100)呈阳性。组织形态学特征和免疫组化结果与人的软骨样脊索瘤一致。本文描述了该病例的组织形态学特征和免疫组织化学结果,并回顾相关文献资料,可以为该肿瘤的诊疗和预后提供参考依据。

Abstract: A 3-year-old, male domestic Anglo mink was presented with a slow-growing mass on the tail tip. The mass was completely removed by surgery. Histological examination performed on the mass revealed a lobulated neoplasm composed of large polygonal cells replaced the last coccygeal vertabra. The neoplastic cells had highly vacuolated cytoplasm (physaliferous cells) and intracytoplasmic Periodic Acid-Schiff-positive granules. Immunohistochemistry revealed cytoplasmic positivity for cytokeratin, vimentin and S-100. Histomorphological features and immunohistochemical results consistent with a chondroid chordoma of humans. This case report described Histomorphological features and immunohistochemical results in chondroid chordoma located at the tail of Anglo mink, and reviews the relevant literature, which can provide a reference for the diagnosis and prognosis of the tumor.

Key words: Anglo mink, tail, chondroid chordoma, histopathology, immunohistochemistry
