Classical Hodgkin lymphoma, mixed cellularity, NOS
Hodgkin lymphoma, mixed cellularity, NOS
Subtype of classic Hodgkin's lymphoma (HL), classic Reed-Sternberg (RS) cells with prominent inclusion-like nucleoli, lacunar cells inconspicuous, nodular fibrosing sclerosis absent. Usually associated with diffuse architectural effacement. Rich inflammatory background with numerous eosinophils, plasma cells, histiocytes.
Mixed cellularity classical Hodgkin lymphoma (MCCHL) frequently involves peripheral lymph nodes. Mediastinal involvement is uncommon. The spleen is involved in 30%, bone marrow in 10%, liver in 3%, and other organs in 1-3%. MCCHL is more frequent in patients with HIV infection and in developing countries. The median age is 38 years and approximately 70% are male. With current regimens MCCHL has approximately the same prognosis as nodular sclerosis and a better prognosis than lymphocyte-depleted 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.
