Abstract

Granuloma annulare (GA) is a benign, self-limited condition which the etiology remains unknown. It is clinically characterized as annularly, erythematous papules on the extremities. Histologically, it shows as palisading granulomas with central degenerated collagen and mucin deposits. The patient in this case report had a rare GA variant named patch-type GA. It appeared as asymptomatic erythematous macules with central clarification on the upper portion of thighs. Histopathology was compatible with interstitialtype GA. We highlight that a high index of suspicion is necessary to make the diagnosis of patch-type GA and confirmation can only be achieved through histopathology study
