Subcutaneous granuloma annulare – a case report and literature review

Abstract

Granuloma annulare (GA) is a chronic, idiopathic dermatosis with tendency to spontaneous resolution. GA has distinct histopathological features including collagen degeneration associated with granulomatous inflammation. It is estimated that condition affects 0.1–0.4% of dermatology patients. Subcutaneous GA is a rare variant of the disease. The authors present a case of a 3-year-old boy diagnosed with subcutaneous GA, successfully treated with local cryotherapy.
