Rheumatoid Neutrophilic Dermatitis: Case Report and Review

Rheumatoid neutrophilic dermatitis (RND) is a rare cutaneous condition that manifests in patients with rheumatoid arthritis (RA) and is characterized by erythematous papules, plaques, nodules, and urticarial lesions on joints, extensor surfaces of the extremities, and the trunk. Although the condition most commonly is reported in patients with severe seropositive RA, it also presents in patients with seronegative RA and must be differentiated from other neutrophilic dermatoses. Because the lesions have a cosmetic effect on patients, managing the underlying RA may help improve cutaneous manifestations of RND. We report a case of RND in a woman with RA and review the literature on
the condition.
