A case report of rheumatoid neutrophilic dermatitis in a Chinese woman with seropositive rheumatoid arthritis

Rheumatoid arthritis (RA) is a chronic inflammatory arthritis associated with a number of extra-articular manifestations. We report the case of a rare extra-articular manifestation of seropositive RA in a 48-year-old woman. She developed spontaneously remitting pustular rashes on the dorsum of both hands which recurred during periods of a high disease activity. Skin biopsy revealed rheumatoid neutrophilic dermatosis (RND), a rare skin manifestation of RA. Both RA and RND were controlled with rituximab therapy. Clinical presentations and differential diagnoses were discussed. Tight control of RA is pivotal in the management of RA and extra-articular manifestations.
