Chondroblastoma of the carpals is rare, can mimic other benign bone tumors, and presents a diagnostic challenge. There have been few cases of benign tumors involving the hamate, with only one reported case of chondroblastoma, which was treated with complete hamate excision. We present a case of chondroblastoma with secondary aneurysmal bone cyst of the hamate treated with curettage, high-speed burring, phenol, and autogenous iliac crest bone grafting. At the time of the most recent radiographic follow-up, there was full graft incorporation, preserved hamate morphology, and no evidence of recurrence.
腕骨软骨母细胞瘤罕见，可模仿其他良性骨肿瘤，带来诊断挑战。累及钩骨的良性肿瘤病例很少，仅有1例软骨母细胞瘤的报道，采用了钩骨完整切除治疗。我们报告1例钩骨软骨母细胞瘤伴继发性动脉瘤样骨囊肿，采用刮除、高速磨钻、苯酚和自体髂嵴植骨治疗。在最近的影像学随访时，植骨完全融合，钩骨形态保留，无复发迹象。
