Amyloidosis Localized (ALoc)
Type of disease: Genetic, autosomal dominant | Rare conditions
Localized amyloid deposits in the airway (trachea or bronchus), eye, or urinary bladder are made up of light chain proteins, similar to those in AL amyloidosis. However, in localized amyloidosis the abnormal plasma cells producing the amyloid light chains are in the tissues, not in the bone marrow. Other localized types of amyloidosis are associated with hormone proteins, aging, or specific areas of the body, and have not been found to develop into systemic amyloidosis.
