MANRIQUEZ, Juan; GIESEN, Laura; PUERTO, Constanza del  e  GONZALEZ, Sergio. Rheumatoid arthritis and pseudo-vesicular skin plaques: rheumatoid neutrophilic dermatosis. An. Bras. Dermatol. [online]. 2016, vol.91, n.4, pp.500-502. ISSN 1806-4841.  https://doi.org/10.1590/abd1806-4841.20164104.

A 54 year-old woman with a 3-year history of rheumatoid arthritis (RA) consulted us because of weight loss, fever and skin eruption. On physical examination, erythematous plaques with a pseudo-vesicular appearance were seen on the back of both shoulders. Histological examination was consistent with rheumatoid neutrophilic dermatosis (RND). After 3 days of prednisone treatment, the skin eruption resolved. RND is a rare cutaneous manifestation of seropositive RA, characterized by asymptomatic, symmetrical erythematous plaques with a pseudo-vesicular appearance. Histology characteristically reveals a dense, neutrophilic infiltrate with leucocitoclasis but without other signs of vasculitis. Lesions may resolve spontaneously or with RA treatment. This case illustrates an uncommon skin manifestation of active rheumatoid arthritis.
