Monoclonal immunoglobulin deposit disease (MIDD) is a rare type of paraproteinaemia that is characterized by the presence of monoclonal deposits of immunoglobulins in the basal glomerular membrane, manifesting more frequently in the fifth and sixth decade of life. MIDD is subclassified as light chain deposit disease (LCDD), heavy chain deposit disease (HCDD) and light and heavy chain deposit disease (LHCDD), with LCDD being the most frequent form of presentation where kappa light chains are identified in up to 80%, associated with multiple myeloma in up to 50% of. The finding of nodular sclerosis can be associated with LCDD in most patients.
