Palisaded Neutrophilic Granulomatous Dermatitis in a Child with Juvenile Idiopathic Arthritis on Etanercept.

Palisaded neutrophilic granulomatous dermatitis (PNGD) is a rare neutrophilic dermatosis that may be associated with significant morbidity because of associated pruritus and pain. It is typically seen in adults with collagen vascular diseases, but may be associated with medications as well. PNGD is rarely reported in children. We describe a girl with polyarticular juvenile idiopathic arthritis who developed PNGD after administration of etanercept and demonstrated rapid and significant improvement upon treatment with topical triamcinolone 0.1% ointment.
