[AL Amyloidosis].

ABSTRACT

AL amyloidosis, derived from amyloidogenic immunoglobulin light chains, is a common type of systemic amyloidosis. Peripheral neuropathy has been identified in 10%-40% of patients with systemic AL amyloidosis. Definitive diagnosis requires tissue biopsies, including skin, fat, and gastrointestinal samples, as well as amyloid typing. Disease-modifying therapies have been shown to improve patient survival and prevent progressive organ dysfunction.
