Primary amyloidosis with dry eyes and dry mouth--a case report
Japanese Journal of Medicine
|November 1, 1991
Abstract:
We report a rare case of dry eyes and dry mouth caused by primary amyloidosis. A 66-year-old woman with keratoconjunctivitis sicca and xerostomia died of acute respiratory failure. Shirmer's test, gum test, and sialography indicated Sjögren's syndrome. Lip biopsy revealed amyloid deposition around the salivary ducts. Bence-Jones protein was noted in the urine. At autopsy, amyloid deposition was identified histochemically in many organs, mainly on the vessel walls. Primary amyloidosis should be considered as a differential diagnosis of Sjögren's syndrome.

Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...
