Patch granuloma annulare:Clinicopathological characteristics and response to phototherapy

Abstract

Granuloma annulare (GA) is a benign cutaneous disease. Clinical variants include classic, generalized, perforating, subcutaneous and patch type GA. Patch GA shows a distinct clinical presentation of smooth erythematous to brownish macules surfacing on the extremities and trunk with no evidence of papules or induration. Diagnosis is usually made by histopathology revealing a pattern of interstitial GA.
