Tumoral calcinosis is a rare and benign subtype of calcinosis cutis, a group of disorders involving soft tissue calcium deposition. Only 250 cases have been described since 1898; hand involvement is exceedingly rare. We report a case of extensive calcinosis within the flexor sheath of the little finger. Presentation included a painful mass over the volar aspect of the little finger, restricted digit motion, and skin compromise at the site of the mass. Surgical debulking was performed resulting in restoration of finger function.
肿瘤性钙化症是钙化性皮肤病的一种罕见良性亚型，这类疾病涉及软组织钙沉积。自 1898 年以来，仅描述了 250 例病例；手部受累极其罕见。我们报告了一例小指屈肌腱鞘内广泛钙化的病例。临床表现包括小指掌侧出现疼痛性肿块，手指运动受限，肿块部位皮肤受损。手术切除肿块后，手指功能得到恢复。
