Introduction
RA is a common inflammatory synovial disorder characterized by
symmetrical polyarthritis and associated with joint destruction
(1, 2). RA
has a broad spectrum clinical manifestation of various organs.
Extra-articular findings and lesions due to skin involvement may also
co-exist which include vasculitis, pyoderma gangrenosum, rheumatoid
nodules and leg ulcers (3,
4). In addition to these findings, palmar
erythema, urticaria, vitiligo, neutrophilic lobular panniculitis and RND
may less commonly occur (5-7).
RND typically progresses in severe RA several years after the diagnosis
of RA and manifests as symmetric erythematous and urticarial lesions
over the extensor surfaces of the extremities
(8). Dermatological involvement tends to
occur in patients with more severe or active RA
(9, 10).
Here, we present a case of RND, a rare neutrophilic skin condition, in a
seronegative RA Sudanese patient treated with cyclosporine.
