骨巨细胞瘤,又称破骨细胞瘤,为原发骨组织肿瘤之一,局部破坏性较大,是生长活跃的肿瘤。经常有复发、恶变转移的倾向。 我院收治3例骨巨细胞瘤行搔刮术或截骨3例中2例为短管状指骨,搔刮术后未行植骨,1例尺骨下端截骨,植骨术后观察2年。3例骨巨细胞瘤,例1,男性,10岁,近节第二指骨;例2,男性,16岁,近节第一拇指指骨;例3,男性,18岁,尺骨下端,拍片骨呈不规则小泡沫溶骨改变,向一侧扩张膨胀,骨皮质变薄,软组织肿胀,未侵蚀骨骺线,指骨两骨骺端有部分正常骨小梁,病理回报,骨巨细胞瘤(Ⅱ级)。
Giant cell tumor of bone, also known as osteoclastoma, is one of the primary bone tissue tumors. It is locally destructive and is an active tumor. There is often a tendency of recurrence and metastasis. In our hospital, 3 patients with giant cell tumor of bone were treated with palatoplasty or osteotomy. Two of them were short tubular phalanges. No bone grafting was performed after blunt scraping. In one case, the lower ulna osteotomy was performed. The bone graft was observed for 2 years. 3 cases of giant cell tumor of bone, case 1, male, 10 years old, proximal second phalanx; case 2, male, 16 years old, proximal first phalangeal phalanx; case 3, male, 18 years old, lower ulnar, showing bone The irregular small foam osteolytic changes, expansion to one side expansion, thinning of cortical bone, soft tissue swelling, no erosion of the epiphyseal line, some normal trabecular bone at the sacral end of the phalanx, pathological return, giant cell tumor of bone (grade II).
