A case of atypical granuloma annulare involving both ears.
We report a rare case of granuloma annulare (GA), affecting both ear antihelixes, in a 28-year old male patient that presented with a 1-year history of non-tender, firm, skin-colored, 1~5 mm papules on both ear antihelixes. There was no history of trauma. An excisional biopsy specimen taken from one of the lesions of the right ear revealed infiltration of histiocytes and lymphocytes around a zone of collagen alteration in the dermis. Based on the clinical and pathological findings, the patient was diagnosed with a rare case of bilateral GA of both antihelixes; this is the first report in the Korean dermatology literature.
