gamma heavy-chain disease

Friday 23 March 2012

Gamma heavy-chain disease (gHCD) is defined as a lymphoplasmacytic neoplasm that produces an abnormally truncated immunoglobulin gamma heavy-chain protein that lacks associated light chains.

gHCD is associated with a variety of underlying lymphoproliferative disorders but most often shows features that overlap with cases previously reported as "vaguely nodular, polymorphous" LPL.

The routine evaluation of small B-cell neoplasms with plasmacytic differentiation could represent a heavy-chain disease and give suggestions for an improved approach to the WHO classification of gHCD.
