Abstract

Calcinosis cutis is a rare disorder characterized by of deposition of insoluble calcium salts in the skin and subcutaneous tissue. Five subtypes of calcinosis cutis are described: dystrophic, metastatic, idiopathic, iatrogenic, and calciphylaxis.1 Of these subtypes, dystrophic calcinosis (DC) is the most common, and it is the most frequently seen in association with underlying autoimmune connective tissue diseases.2 Dermatomyositis, systemic sclerosis and less commonly systemic lupus erythematous were described to be complicated by DC. However, DC associated with rheumatoid arthritis (RA) is extremely rare.2 The condition causes substantial morbidity and is associated with pain and limitation of movement when the process involves areas close to joints or when ulceration occurs.2 We report a middle age Sudanese woman with good controlled RA who developed dystrophic calcinosis cutis.
膝关节肌细胞瘤病例报告及文献复习
皮肤钙化症是一种罕见的疾病,其特征是不溶性钙盐沉积在皮肤和皮下组织中。皮肤钙沉着病有五种亚型:营养不良、转移性、特发性、医源性和钙化性。1在这些亚型中,营养不良钙沉着病(DC)最常见,也是最常见的与潜在的自身免疫性结缔组织疾病相关的疾病。2皮肌炎,系统性硬化和不太常见的系统性红斑狼疮被描述为并发DC。然而,与类风湿性关节炎(RA)相关的DC极为罕见。2当该过程涉及关节附近区域或发生溃疡时,这种情况会导致严重的发病率,并与疼痛和行动受限有关。2我们报告了一名患有良好控制的RA的中年苏丹妇女,她患上了营养不良的钙化性皮肤病。
