We report the case of an 80-year-old woman who presented with an asymptomatic slowly growing mass in the dorsal aspect of her right wrist. Radiographs revealed a snail-shaped radiopaque structure. Surgical exploration and excision revealed a calcified lesion over the extensor digitorum communis. Histopathological analysis confirmed the diagnosis of tenosynovial chondromatosis. At the last follow-up, four years after surgery, the patient was asymptomatic and free of recurrence. Practitioners and hand surgeons should be aware of the dorsal involvement and evocative radiological calcifications of tenosynovial chondromatosis, which is a rare benign soft tissue neoplasm that affects all tendon sheaths of the hand.
我们报告了一例 80 岁女性病例，其右侧腕背部出现无症状、缓慢生长的肿块。X 线片显示为蜗牛形不透射线结构。手术探查和切除显示伸指总肌腱上有钙化病变。组织病理学分析证实了腱鞘滑膜软骨瘤病的诊断。在最后一次随访时，即手术后四年，患者无症状且无复发。临床医生和手外科医生应该意识到腱鞘滑膜软骨瘤病的背侧受累和提示性放射学钙化，这是一种罕见的良性软组织肿瘤，影响手部所有肌腱鞘。
