A case of primary systemic amyloidosis.
An adult patient with primary systemic amyloidosis associated with nephrotic syndrome and complete atrial-ventricular (A-V) block is described. This case was considered to be a slowly progressive primary amyloidosis because of a long time episode of poor appetite and nephrotic syndrome. Temporal pace making of the heart was not effective presumably due to heart muscle damage, pér sé. Autopsy specimens revealed typical features of primary amyloidosis in light microscopy and immunofluorescence. It is suggested that early detection of amyloid fibers in the heart muscles may improve prognosis in patients with primary amyloidosis.
