Abstract
Hepatic amyloid, when identified, is usually located in the sinusoids, portal tracts, and arterioles. We report 14 cases of hepatic amyloidosis where eosinophilic globules having the histochemical and electron microscopic features of classic amyloid were found. The globules were round to oval, 5 to 40 μm in diameter, and were found within the space of Disse as well as aggregated within the portal tracts. There were no distinctive clinical or laboratory features distinguishing this type of amyloidosis from classic hepatic amyloidosis. However, there were no cases of multiple myeloma and only one of benign monoclonal gammopathy. All seven patients who were studied at postmortem examination had systemic (nonglobular) amyloidosis. This form of hepatic amyloidosis is probably not an early form of the disease but is an original but rare presentation of hepatic amyloid deposition.
