Abstract:
Rheumatoid neutrophilic dermatitis (RND) is a rare extra-articular skin lesion associated with rheumatoid arthritis (RA). Lesions typically occur symmetrically on the extensor surfaces of the extremities and present with variable clinical features. A 78-year-old female with a 2-month history of skin rash on the right forearm and left lower leg, with no other systemic symptoms, visited the dermatology department of our hospital. She had been diagnosed with seropositive RA approximately 20 years ago. The skin rash was asymmetrically distributed and presented with localized pustules, purpura, and edema. The biopsy specimen showed dermal infiltration by neutrophils, leukocytoclasia without vasculitis, and a neutrophilic dermal abscess. No fungi or bacteria were detected on any of the stains. The patient was diagnosed with RND. Clinical improvement was noted after treatment with dapsone, followed by colchicine and methylprednisolone. In this case report, we described the case of a female patient with atypically presented RND and conducted a literature review.
