title: A case of hereditary amyloidosis transthyretin variant Met 30 with amyloid cardiomyopathy, less polyneuropathy, and the presence of giant cells.
abstract: Transthyretin-Met 30 (TTR-Met 30) is a variant of transthyretin and is usually associated with familial amyloid polyneuropathy. It is rare that patients with TTR-Met 30 will primarily develop amyloid cardiomyopathy. This report presents a patient with late-onset TTR-Met 30 who primarily developed amyloid cardiomyopathy, with less amyloid polyneuropathy in the peripheral nervous system than is usually seen. An autopsy was performed, and histological examination revealed many foreign-body giant cells and macrophages in the area of amyloid deposition that was found in nearly all of the organs.
