Abstract

|
Palisaded neutrophilic and granulomatous dermatitis (PNGD) is characterized histopathologically by the presence of granulomatous inflammation with or without leukocytoclastic vasculitis. It has been associated with multiple systemic diseases, particularly autoimmune conditions like rheumatoid arthritis and Behcet’s disease. We report a 52-year-old woman with rheumatoid arthritis who presented with a single, non-tender, rapidly growing nodule on her right elbow. Histologic examination of the nodule revealed degenerated collagen, neutrophils, neutrophilic dust, fibrin, and mucin present in the centers of the palisades of histiocytes throughout the dermis. Herein, we report the abrupt onset of PNGD in a patient with rheumatoid arthritis.
