Primary-localized-cutaneous-amyloidosis: Lichen amyloidosus

Abstract

This case report presented a female patient with primary-localized-cutaneous--amyloidosis in the form of lichen amyloidosus. Primary-localized-cutaneous--amyloidosis is a rare idiopathic dermatosis caused by abnormal deposition of amyloid composed primarily of degenerated keratin filaments. In order to establish the final diagnosis, detailed clinical and laboratory investigations were performed, with a particular emphasis on pathohistological analysis of skin specimens, special stains, and electron microscopy.
