title: Immunotactoid-like glomerulopathy with massive fibrillary deposits in liver and bone marrow in monoclonal gammopathy.
abstract: At autopsy, massive nonamyloid fibrillar deposits, immunoreactive to IgG and kappa light chain, were found in glomeruli, liver, and bone marrow of a 72-year-old woman. The patient suffered from severe nephrotic syndrome, hepatomegaly and cholestasis, normochromic anemia, and IgG kappa monoclonal gammopathy. Fibrillary glomerulopathies, most often denoted as fibrillary glomerulonephritis or immunotactoid glomerulopathy, are generally considered to have deposits restricted to the glomeruli. However, this study indicates that fibrillary deposits may be a systemic manifestation of fibrillary glomerulonephritis or immunotactoid glomerulopathy, at least when the patient is suffering from a monoclonal gammopathy.
