Interstitial granulomatous dermatitis in a patient with systemic lupus erythematosus: First case report in Saudi Arabia

Abstract Interstitial granulomatous dermatitis (IGD) is an uncommon idiopathic dermatitis characterized by variable clinical presentation and a special histopathologic pattern. IGD is in some cases associated with autoimmune connective tissue diseases. Here we describe, IGD in a 35 year old Saudi female systemic lupus erythematosus patient. IGD lesions appeared as multiple asymptomatic erythematous annular plaques symmetrically distributed in the axillae, chest, abdomen and back. The lesions resolved totally within 2 months after systemic corticosteroid treatment.
