Clinical manifestations of primary amyloidosis can be subtle, particularly when the gastrointestinal tract is involved. We present two cases that illustrate the diversity of such involvement and the subsequent problems with diagnosis. Gastrointestinal effects of primary systemic amyloidosis are reviewed and clinical pointers towards diagnosis are discussed. In particular these cases illustrate ...

Primary localized amyloidosis is a rare disease with an excellent prognosis in most cases. We report a case of primary localized amyloidosis of the bladder that was treated with transurethral resection.

Primary localized cutaneous nodular amyloidosis (nodular amyloidosis) is a rare and distinct type of amyloidosis, in which amyloid L deposition is limited to the skin and typically manifested as a tumefactive nodule on the acral sites. However, the definite cause of nodular amyloidosis is still unknown. Although it is relatively well known that the amyloid deposits in nodular amyloidosis origin...

Amyloidosis is characterized by an abnormal extracellular deposition of amyloid in different organs, where it usually causes some type of dysfunction. Its cause is unknown. Five different types of amyloidosis have been described according to the underlying disease; immunoglobulin amyloidosis, familial amyloidosis, senile systemic amyloidosis, secondary amyloidosis and hemodialysis-associa...

Amyloidosis is characterized by a deposition of insoluble fibrils in various organs and tissues. Amyloid deposition, in the gastrointestinal track, provokes a dysfunction of the organ, due to an accumulation of fibrils, and causes a variety of clinical symptoms and endoscopic findings. Primary amyloidosis in the gastrointestinal tract is rarely reported in Korea. We experienced a case of recurr...

We report here on a rare case of primary AL hepatic amyloidosis associated with multiple myeloma in a 64-year-old woman. The patient was referred for evaluating her progressive jaundice and right upper quadrant pain. (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET)/computed tomography (CT) showed diffusely and markedly increased (18)F-FDG uptake in the liver. Although the...

Amyloidosis is characterized by extracellular deposition of abnormal protein, consisting of primary, secondary, hemodialysis-related, hereditary, senile and localized type. Primary amyloidosis is associated with monoclonal light chains. Secondary amyloidosis is associated with inflammatory, infectious, and neoplastic diseases. Amyloid deposition in the gastrointestinal tract can manifest the sy...

Crescentic glomerulonephritis is a rare complication of AA amyloidosis. There are no clinical case reports of this complicating AL amyloidosis. A 67-year-old man developed rapidly progressive glomerulonephritis (RPGN) on a background of primary AL amyloidosis and IgGkappa multiple myeloma. Investigations for causes of glomerulonephritis were negative, and a renal biopsy confirmed crescentic glo...
