Primary cutaneous amyloidosis involving the external ears along with the classical sites.

ABSTRACT

A 26-year-old woman had multiple itchy persistent gradually progressive papular lesions on the forearms and shins for 10 and 4 years respectively. She also noticed similar lesions on both the ears for 4 years. There were no systemic symptoms. Cutaneous examination revealed multiple 2-3 mm discrete firm hyperpigmented papules on the extensors of forearms, shins and earlobes. Skin biopsy from all sites demonstrated deposits of amyloid in the papillary dermis. The patient was treated with cyclophosphamide 50 mg daily orally. There was more than 50% improvement in her lesions.
