Cutaneous granulomas in rheumatoid arthritis. [Journal Article]
Int J Dermatol 2007 Nov.:33-5.
A 57-year-old man with rheumatoid arthritis and myasthenia gravis developed an asymptomatic erythematous plaque on his nose and skin-colored nodules on the elbows. Histopathological examination was suggestive of palisaded neutrophilic granulomatous dermatitis (PNGD). PNGD is a rather uncommon cutaneous finding in different collagen vascular disorders that can manifest with a broad range of clinical symptoms and histological signs. Based on the case report of the patient described here, we briefly discuss what is currently known about this disease.
