INTRODUCTION
Chondroblastoma is a rare primary benign tumor of bone with male predominance and is typically seen in an epiphyseal location. The pisiform is a carpal bone and chondroblastoma of the pisiform has not been reported in the literature to the best of our knowledge.
CASE PRESENTATION
An 18-year-old male presented with painful swelling over his right wrist with restriction of ulnar deviation. Based on magnetic resonance imaging findings, two diagnostic possibilities were entertained, namely, giant cell tumor of bone and chondroblastoma. Wide local excision was performed, and histopathology confirmed the diagnosis of chondroblastoma of the pisiform. After 2 years of follow-up, the patient has gained pain-free wrist movements post excision, and there are no signs of recurrence. The Modified Mayo Wrist Score of 75 (fair) improved to 100 (excellent).
CONCLUSION
Surgeon should always keep in mind the possibility of the tumor at the rare site and accurately diagnose the tumor with the help of imaging modalities and biopsy.
引言
软骨母细胞瘤是一种罕见的原发性骨良性肿瘤，男性多见，典型地发生于骨骺部位。豌豆骨是腕骨，据我们所知，文献中尚未报道过豌豆骨软骨母细胞瘤。
病例报告
一名18岁男性因右腕疼痛肿胀伴尺侧偏斜受限就诊。基于磁共振成像结果，考虑了两种诊断可能性，即骨巨细胞瘤和软骨母细胞瘤。进行了广泛局部切除，组织病理学证实为豌豆骨软骨母细胞瘤。随访2年后，患者术后腕部活动无痛，无复发迹象。改良梅奥腕关节评分从75分（一般）提高到了100分（优秀）。
结论
外科医生应始终牢记罕见部位肿瘤的可能性，并借助影像学检查和活检准确诊断肿瘤。
