Lobular membranoproliferative glomerulonephritis with organized microtubular monoclonal immunoglobulin deposits associated with B cell small lymphocytic lymphoma
| The first 10% of the full text of this article appears below. |
Sir,
Fibrillary glomerulonephritis (FGN) and immunotactoid glomerulopathy (ITG) are well known glomerular diseases with Congo-red-negative deposits [14]. While FGN is characterized by randomly arranged microfibrils around 20 nm in diameter with no underlying systemic disorder, ITG is defined by orderly arranged microtubular deposits, usually >30 nm in diameter with a hollow core; patients with ITG tend to have underlying lymphoproliferative diseases.
