Primary Site(s)

C770-C779
Lymph nodes (C770-C779) are the usual primary sites; however, involvement in other sites is possible. If you have confirmation that the only involved site is something other than the lymph nodes, then code to that primary site. See also Module 7.

Abstractor Notes

Lymphocyte-rich classical Hodgkin lymphoma (LRCHL) typically involves peripheral lymph nodes. Mediastinal involvement and bulky disease are uncommon. Most patients present with stage I or II disease. B symptoms are rare.

Clinical features are similar to those of NLPHL with the exception that multiple relapses seem to occur less frequently. With modern risk-adjusted treatment, survival and relapse free survival are slightly better than the other subtypes of CHL.

Diagnostic Confirmation

This histology can be determined by positive histology (including peripheral blood) with or without genetics and/or immunophenotyping. Review the Definitive Diagnostic Methods, Immunophenotyping and Genetics Data sections below, and the instructions in the Hematopoietic Manual for further guidance on assigning Diagnostic confirmation.

Definition

Lymphocyte-rich classic Hodgkin lymphoma (LRCHL) is a subtype of classic Hodgkin lymphoma (CHL) characterized by scattered Hodgkin/Reed-Sternberg (HRS) cells and a nodular or (less often) diffuse cellular background consisting of small lymphocytes, with an absence of neutrophils and eosinophils.
