A Case of Lichen Amyloidosis on the Auricular Concha and a Review of the Literature / 대한피부과학회지

ABSTRACT

Lichen amyloidosis is composed of firm, yellowish to brownish papules, usually found on the pretibial area. Amyloidosis of the auricular concha is a rare variant of primary cutaneous amyloidosis, presenting papules or plaques localized to the ear. Histopathologically, it is characterized by hyperkeratosis, acanthosis and deposition of eosinophilic materials in the papillary dermis similar to the presentation of lichen amyloidosis. Herein, We report a case of lichen amyloidosis occurring on the auricular concha of a 48-year-old Korean woman, presented with a 3-years history of asymptomatic monomorphous papules on her both ears.
