Amyloidosis: Systemic, Nodular, and Epidermal Derived

Abstract

The amyloidoses encompass a broad category of cutaneous and systemic disorders with important pathogenic consequences. These derive from the direct deposition of abnormal proteins or indirectly relate to potentially deadly systemic disorders that produce such deposits. Each of the amyloidoses can be defined by certain histomorphologic and chemical properties that permit their identification and inclusion into disease categories (1). These designations can be loosely grouped into systemic and cutaneous delimited forms.
