Papules in the auricular concha: lichen amyloidosus in a case of biphasic amyloidosis

M A Barnadas et al. Dermatologica. 1990.

Abstract

We present a patient with lichen amyloidosus on the ears and macular amyloidosis on the back. These diagnoses were supported by histological, histochemical and immunohistochemical studies. This is to the best of our knowledge the first reported case of a biphasic form of amyloidosis whose lichenoid counterpart consists of papules on the ears. This suggests that primary cutaneous localized amyloidosis may have peculiar clinical manifestations depending on the location of the lesion.
