Sweet’s syndrome
A 52-year-old woman who was taking immunosuppressive therapy for rheumatoid arthritis presented with a 1-month history of painful plaques on both palms and fingers. Her maintenance medications for rheumatoid arthritis included sulfasalazine and azithioprine. In addition to the skin lesions which were limited to the palms and fingers, physical examination revealed ulnar deviation and Z deformity of both hands consistent with chronic changes due to rheumatoid arthritis. A skin biopsy revealed papillary dermal edema, perivascular and interstitial lymphohistiocytic and neutrophilic infiltration consistent with the inflammatory disorder sweet's syndrome or acute febrile neutrophilic dermatosis.
