ICD-11 definition : Amyloidosis is a vast group of diseases defined by the presence of insoluble protein
deposits in tissues. Its diagnosis is based on histological findings. Amyloidoses
are classified according to clinical signs and biochemical type of amyloid protein
involved. Most amyloidoses are multisystemic, 'generalized' or 'diffuse'. There are
a few forms of localized amylosis. The most frequent forms are AL amyloidosis (immunoglobulins),
AA (inflammatory), and ATTR (transthyretin accumulation).;
