In this 72‐year‐old male patient, large amounts of amyloid substances were deposited in the mesenchymal organs, but not in the parenchymal organs. Histochemical and electron microscopic studies revealed large amounts of amyloid substances and amyloid fibrils in the skeletal and smooth muscle tissues. In the skeletal muscle tissues, where large amounts of amyloid substances were deposited, glycosaminoglycan was also markedly deposited, especially chondroitin‐4‐sulfuric acid. The concentrations of silicon were also markedly increased in the amyloid fibrils. The concentrations of nickel and cobalt were increased but those of zinc were decreased in all organs measured, although both nickel and cobalt in another case of amyloidosis experienced were within normal values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
