Primary Site(s)
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.

Code grade specified by pathologist. If no grade specified, code 9

Alternate Names
Hodgkin disease, lymphocyte predominance, NOS [OBS]
Hodgkin disease, lymphocyte-predominance, diffuse [OBS]
Hodgkin disease, lymphocytic-histiocytic predominance [OBS]
Subtype of classical Hodgkin lymphoma characterized by background of abundant small lymphocytes. Reed-Sternberg cells have classic morphology and immunophenotype. Most common growth pattern nodular, diffuse pattern rarely seen. 40% associated with EBV.

Lymphocyte-rich classical Hodgkin lymphoma is a subtype of classical Hodgkin lymphoma with scattered Hodgkin and Reed-Sternberg cells with a nodular or less often diffuse cellular background consisting of small lymphocytes and an absence of neutrophils and eosinophils.
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.

Per WHO, Hodgkin lymphomas are primarily B-cell lymphomas. If the medical record states B-cell, code 6. Since there are Hodgkin lymphomas that are not B-cell, the default grade is 9 (unknown) where the documentation does not specifically state B-cell.
