Description
Summary:Abstract Besides being an uncommon clinicopathological entity, interstitial granulomatous dermatitis, also described as interstitial granulomatous dermatitis with arthritis (IGDA), has shown a wide spectrum of clinical manifestations, such as linear and erythematous lesions, papules, plaques and nodules. Histological features include dense dermal histiocytic infiltrate, usually in a palisade configuration, and scattered neutrophils and eosinophils. We describe a middle aged woman with rheumatoid arthritis of difficult management and cutaneous lesions compatible with IGDA.
