Calcinosis cutis is a rare condition characterized by the deposition of insoluble calcium salts in the skin and subcutaneous tissue. Dystrophic calcinosis cutis appears as a result of local tissue damage or abnormalities, such as alterations in extra-cellular matrix proteins or subcutaneous tissue with normal calcium and phosphate serum levels. It has been rarely described as a late complication of burns. Latency periods of 15-54 years have been reported. We describe the case of a 57-year-old man with dystrophic calcinosis cutis in a burn scar, which developed 42 years after the skin injury. The condition was successfully treated with surgical excision.
皮肤钙化症是一种罕见的病症，其特征是不溶性钙盐沉积于皮肤和皮下组织。营养不良性皮肤钙化症是局部组织损伤或异常所致，比如细胞外基质蛋白或皮下组织发生改变，而血清钙和磷水平正常。它很少被描述为烧伤的晚期并发症。据报道，潜伏期为15至54年。我们描述了一例57岁男性患者，其烧伤瘢痕处出现营养不良性皮肤钙化症，该病症在皮肤损伤42年后发生。通过手术切除，病情得到成功治疗。
