title: Rheumatoid neutrophilic dermatitis.
abstract: Three cases of rheumatoid neutrophilic dermatitis, a specific entity that occurs in association with rheumatoid arthritis, are presented. Clinically, the condition presents as papules and nodules on the dorsal aspect of the fingers, the extensor aspect of the forearms, and the thighs. Like some other neutrophilic dermatitides, it is characterized histologically by a dense, diffuse infiltrate of neutrophils throughout the dermis. The cause of this neutrophilic infiltrate is not known.
