SEER is an authoratitive source of information on cancer incidence and survival in the United States. SEER currently collects and publishes cancer incidence and survival data from population-based cancer registries covering approximately 28 percent of the U.S. population.
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.
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. The 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 progression free survival are slightly better than the other subtypes of CHL.
Preferred primary sites are listed for this disease in the primary site field; however, involvement in other sites is possible, but rare. If you have confirmation that the only involved site is something other than the preferred primary listed, then code to that primary site.
