Definition / general
- Lymphoplasmacytic neoplasm that produces an abnormally truncated immunoglobulin heavy chain protein that lacks associated light chains (eMedicine: Gamma Heavy Chain Disease [Accessed 17 January 2018])
- Less common than light chain deposition disease
- May have milder hematological disorders than in light chain deposition disease (Clin Nephrol 2009;71:9)
- Associated with various lymphoproliferative disorders, but usually has features overlapping with cases previously reported as "vaguely nodular, polymorphous" lymphoplasmacytic lymphoma (Am J Surg Pathol 2012;36:534)
Case reports
- 51 year old man with linear deposits of gamma 4 heavy chains along glomerular, tubular and vascular basement membrane and in mesangial regions (Mod Pathol 1994;7:874)
- 68 year old woman with gamma 1 heavy chain disease (Intern Med 2010;49:1411)
- Monotypic mu heavy chain mesangial deposits causing nodular glomerulosclerosis in woman without evident hematopoietic malignancy (Hum Pathol 2000;31:122)
- Follow up biopsy post chemotherapy showed remarkable diminution of both nodular glomerular lesions and IgG heavy chain deposits (Clin Nephrol 2008;69:383)
Immunofluorescence description
- IgG heavy chains along glomerular, tubular and vascular basement membranes and in mesangium
- No light chain deposition
