Twenty percent of people with AL amyloidosis have an enlarged tongue, that can lead to obstructive sleep apnea, difficulty swallowing, and altered taste. [6] Tongue enlargement does not occur in ATTR or AA amyloidosis. [5] Enlarged shoulders, "shoulder pad sign", results from amyloid deposition in synovial space. Deposition of amyloid in the throat can cause hoarseness. [5] Aß2MG amyldoisis (Hemodialysis associated amyloidosis) likes to deposit in synovial tissue causing chronic synovitis which can be lead to repeated carpel tunnel syndrome.
Amyloid disease: A disease characterised by the deposition of amyloid in various organs of the body. It is generally considered that the amyloidoses share common pathogenic mechanisms which lead to protein fibril formation and deposition. These mechanisms may include structural, metabolic, genetic and environmental factors that may be common to all forms of amyloidosis. Primary amyloidosis, while the most common form of amyloidosis, is a sporadic disease and, therefore, can only be investigated on a case by case basis.
