This is an important pitfall to recognize because t cell lymphomas and classical hodgkin lymphomas frequently present with similar mixed inflammatory.

Reed sternberg cells also known as lacunar histiocytes for certain types are distinctive giant cells found with light microscopy in biopsies from individuals with hodgkin lymphoma they are usually derived from b lymphocytes classically considered crippled germinal center b cells in the vast majority of cases the immunoglobulin genes of reed sternberg cells have undergone both v d j. A doctor can tell the difference between hodgkin s lymphoma and non hodgkin s lymphoma by examining the cancer cells under a microscope. Hodgkin s lymphoma is a primary malignant tumor of the lymph nodes rarely affecting the extranodal lymphoid tissue. Reed sternberg like cells in t cell lymphomas typically present with a b cell immunophenotype.
