小型犬股骨头骨巨细胞瘤的诊治

Diagnosis and Treatment of Giant Cell Tumor of Femoral Head in a Small Dog

骨巨细胞瘤(giant cell tumor of bone,GCTB)是一种由梭状肿瘤间质细胞和多核巨细胞组成的溶骨性骨肿瘤,具有较强的侵袭性和转移能力,对骨质破坏明显。1只法国斗牛犬左后肢轻度跛行,通过临床症状观察、血常规检查、荧光免疫检查、X射线检查和骨组织病理切片观察等综合诊断,确诊该犬左后肢股骨头处患有GCTB。采用手术切除股骨头的治疗方案,术后犬股骨头部位恢复良好,复查无瘤细胞扩散,3个月后患犬完全恢复正常。由此可见,小型犬股骨头GCTB采用完全切除的方式可以起到较好的治疗效果。本文为小型犬GCTB的临床诊断和治疗提供了参考。
