Skin manifestations associated with rheumatoid arthritis.
We examined cutaneous manifestations of rheumatoid arthritis (RA) of 142 Japanese patients who visited both the Departments of Dermatology and Rheumatology of our hospital. We classified cutaneous lesions into specific and/or characteristic or nonspecific ones. Nonspecific lesions predominated in our series. Among the specific skin manifestations, which comprised 10% of the total, rheumatoid nodules, rheumatoid papules, rheumatoid neutrophilic dermatitis, and severe vasculitic ulcers correlated with high titers of rheumatoid factors and progression of RA, while purpura and livedo did not. Nonspecific skin manifestations failed to correspond with the level of rheumatoid factors. Among the nonspecific lesions, asteatotic eczema, candida interdigitalis, and tinea unguium were commonly detected.
