Palisaded and neutrophilic granulomatous

dermatitis is a rare reactive dermatosis. It may be associated with

rheumatoid arthritis and other chronic inflammatory conditions, such

as systemic lupus erythematosus, vasculitis, autoimmune hepatitis,

inflammatory bowel disease, and sarcoidosis. It has also been

reported in association with malignancies, infectious diseases, and

drug reactions. The exact pathogenesis of palisaded and neutrophilic

granulomatous dermatitis remains unclear. The diagnosis is based on

clinical and histopathological evaluation.

We report a rare case of palisaded and neutrophilic granulomatous

dermatitis associated with rheumatoid arthritis. Treatment with

topical corticosteroids resulted in improvement of the skin lesions.

The patient has been followed for 4 months without recurrence.
