Granuloma annulare presenting as multiple nodules on the pinna

Abstract

Granuloma annulare is a benign, idiopathic, inflammatory dermatosis characterized clinically by dermal papules and annular plaques. We describe the case of a 40-year-old man who presented with a long history of multiple nodules on the left pinna. Histological examination revealed the typical necrobiotic granulomas of granuloma annulare. The condition predominantly affects the extremities of children and young adults; cases involving the pinna are extremely rare.Nodular lesions are common in otolaryngological practice, and this case illustrates the need for careful clinical assessment and appropriate biopsy in diagnosing lesions of the outer ear
