Renal diseases with organized deposits include amyloid, fibrillary, immunotactoid, and cryoglobulinemic glomerulopathies. AL amyloidosis and fibrillary glomerulonephritis are different in the composition of their immunoglobulin deposits. Fibrils of fibrillary glomerulonephritis are usually composed of polyclonal, occasionally oligoclonal or monoclonal, immunoglobin G, but amyloidosis consists of monoclonal light chains. Simultaneous occurrence of fibrillary glomerulonephritis and AL amyloidosis is very rare. We report a case of fibrillary glomerulonephritis combined with AL amyloidosis in a 71-yr-old man.

This review focuses on the clinical use of (18)F-FDG PET to evaluate multiple myeloma. (18)F-FDG PET is useful for diagnosis, staging of multiple myeloma and differential diagnosis of myeloma related disease such as monoclonal gammopathy of undetermined significance or plasmacytoma. For therapy response, (18)F-FDG PET may be effective after chemotherapy for multiple myeloma and radiotherapy for plasmacytoma.

Amyloidosis is a clinical disorder caused by extracellular deposition of proteinaceous insoluble fibrils in various tissues, resulting in organ compromise. Amyloid L (AL) amyloidosis is the most common type of systemic amyloidosis, which occurs in association with multiple myeloma or monoclonal gammopathy of undetermined significance (MGUS). Secondary amyloid A (AA) amyloidosis is a complication of chronic inflammatory conditions, such as rheumatoid arthritis or ankylosing spondylitis. We report a case of a 49-year-old manwith a 11-year history of ankylosing spondylitis, who was recently diagnosed with MGUS presented with cardiac amyloidosis of both the AA and AL types. We report this case along with a review of relevant literature.

Paraproteinemia potentially causes peripheral neuropathy via an unknown underlying pathogenetic mechanism. We report a case of pathologically proven amyloid neuropathy with AL amyloidosis with an IgA kappa light chain, which was initially diagnosed as neuropathy associated with monoclonal gammopathy of undetermined significance. This case indicates that in cases of neuropathy with paraproteinemia, the other potential causes should be excluded by appropriate means, especially pathological evaluations.

Multiple myeloma is a malignant disease of plasma cells, whereas ankylosing spondylitis is a chronic inflammatory disease of axial joints. The relationship between the two diseases is uncertain, but chronic inflammation could trigger multiple myeloma. The authors report the cases of two ankylosing spondylitis patients with a disease duration of more than 20 years, that subsequently developed IgA kappa and IgG lambda chain myeloma, respectively, and discuss the possible pathogenetic relationship between these diseases.
