Amyloidosis refers to a group of disorders in which protein fibers are deposited in tissues and organs, harming them.[1]  AL amyloidosis, also known as primary systemic amyloidosis, is the most common form of amyloidosis.[2] It refers specifically to cases of amyloidosis where the deposits contain bits of immunoglobulin light chain.[3][4] Signs and symptoms depend on the organs affected by the deposits, which may include the tongue, intestines, skeletal and smooth muscles, joints, nerves, skin, ligaments, heart, liver, spleen, and kidneys. AL amyloidosis is related to the plasma cell disorder multiple myeloma. Treatment may include chemotherapy directed at the abnormal plasma cells or stem cell transplantation.[1]
