Amyloid deposits in the periarticular tissue.
Periarticular and peritendinous tissue was investigated in cases of rheumatoid arthritis, osteoarthritis and carpal tunnel syndrome for the appearance of amyloid deposits. In rheumatoid arthritis no amyloid was present. In 7.8% of the cases with osteoarthritis and in 8% of the cases with carpal tunnel syndrome amyloid was present. These amyloid desposits were present essentially in old patients and since no further clinical symptoms of systemic amyloidosis were reported, these deposits are regarded as an age related phenomenon without clinical relevance.
