A doctor can tell the difference between hodgkin s lymphoma and non hodgkin s lymphoma by examining the cancer cells under a microscope. They are large often multinucleated with a peculiar morphology and an unusual immunophenotype that does not resemble any normal cell in the body. This pathway is presumably activated in reed sternberg cells in a paracrine and autocrine fashion but also through genetic lesions see below.

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. Reed sternberg like cells in t cell lymphomas typically present with a b cell immunophenotype. More recently they have also been reported expressing t cell markers while lacking b cell markers. The diagnosis criteria are.

Tests for other proteins may point to nodular lymphocyte predominant hodgkin lymphoma nlphl to non hodgkin lymphoma rather than hodgkin lymphoma or maybe to other diseases. Despite their rarity in hl tissues hrs cells are the clonal t. Hodgkin s lymphoma is a primary malignant tumor of the lymph nodes rarely affecting the extranodal lymphoid tissue. Tumor component reed sternberg cell typical and variants and a reactive component normal mature lymphocytes eosinophils plasma cells neutrophils fibrosis and capillaries.

Reed sternberg cells have an active jak stat signaling pathway the major pathway for cytokine signaling. This is an important pitfall to recognize because t cell lymphomas and classical hodgkin lymphomas frequently present with similar mixed inflammatory.
