A 25-year-old white man had a tender mass on the dorsum of his hand. Routine examination and radiographs revealed a benign lytic neoplasm in the base of the ring metacarpal. The primary treatment consisted of curettage and cancellous bone grafting. The biopsy diagnosis was chondroblastoma. The patient is asymptomatic and has a normal radiograph after a follow-up period of one year. This unusual tumor has seldom been reported at sites distal to the wrist. The report of this chondroblastoma serves as a reminder that not all benign lytic processes in the hand are enchondromas.
一名25岁的白人男性手部背侧有一压痛性肿块。常规检查及X线片显示环指掌骨基部有一良性溶骨性肿瘤。主要治疗方法为刮除术及松质骨移植。活检诊断为软骨母细胞瘤。随访一年后，患者无症状，X线片正常。这种不常见的肿瘤在腕部远端部位很少有报道。该软骨母细胞瘤病例报告提醒我们，手部并非所有良性溶骨性病变都是内生软骨瘤。
