A superficial and deep perivascular and periadnexal dermatitis with interstitial inflammation was present throughout the dermis. Neutrophilic and lymphocytic inflammation, with clusters of histiocytes, was present throughout the interstitium. Results of Gram, acid-fast bacilli, and Alcian blue stainings were negative. Antinuclear antibody findings were positive in a speckled pattern at greater than 1:1280 titer. The IGD diagnosis was suspected clinically, and the patient was treated with intramuscular triamcinolone with rapid improvement in her skin symptoms.
