The phenotypic profile of dermatomyositis and lupus erythematosus: A comparative analysis
Lupus Erythematosus, Cutaneous
Lupus Erythematosus, Systemic
An interferon-alpha-inducible cytokine milieu is common in SLE, DLE, SCLE and DM. In addition, there are phenotypic differences as alluded to above that may be of some practical value in separating these distinctive subsets. Features not previously emphasized such as MXA endothelial cell staining in DM and the lack of staining for CD83 and CLA in lesions of collagen vascular disease may be of diagnostic value.
