Overview
In 1639, Nicolaus Fontanus autopsied a young man who had ascites, jaundice, liver abscess, and splenomegaly and his report has been the first description of amyloidosis. There is no significant data regarding the historical perspective of amyloidosis throughout the 18th century. Rudolph Virchow and Weber are the prominent figures with substantial work on amyloidosis during the 19th century. In 1922, Bennhold introduced Congo Red staining of amyloid that remains the gold standard for diagnosis. There is no established system for the classification of wild-type (senile) amyloidosis. Amyloid is an abnormal insoluble extracellular protein that deposits in the different tissues and causes organ dysfunction and a wide variety of clinical syndromes. Wild-type (senile) amyloidosis is a type of systemic amyloidosis as transthyretin (TTR) deposits can be found throughout the body. TTR results in pathologies due to misfolding, breaking apart, and deposition of the amyloid fibrils in healthy tissue. The condition mainly affects the heart. However, other organ systems, such as the nervous and musculoskeletal systems, can also be involved. There are no genes implicated in the causality of wild-type (senile) amyloidosis. Aging is very strongly associated with wild-type (senile) amyloidosis.

Pathophysiology
Amyloid is an abnormal insoluble extracellular protein that deposits in the different tissues and causes organ dysfunction and a wide variety of clinical syndromes. Wild-type (senile) amyloidosis is a type of systemic amyloidosis as transthyretin (TTR) deposits can be found throughout the body. TTR results in pathologies due to misfolding, breaking apart, and deposition of the amyloid fibrils in healthy tissue. The condition mainly affects the heart.
