Summary
Hodgkin lymphoma (HL) is a family of unique B-lineage lymphoma subtypes and encompasses two morphologically, immunophenotypically, and clinically distinct categories: classic Hodgkin lymphoma (CHL) and nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL). HL usually affects the lymph nodes and is composed of a small number of large, dysplastic mononuclear and multinucleated neoplastic cells (Hodgkin/Reed-Sternberg [HRS] cells, or lymphocyte-predominant [LP] cells/lymphocytic and histiocytic [L&H] cells) set in the background of benign inflammatory elements with or without abundant band-like and/or more diffuse collagen fibrosis. The neoplastic cells are often surrounded by T-lymphocytes [1,2].
The difference between NLPHL and CHL is that the B-cell program is generally preserved, and the neoplastic cells exhibit the overt B-lineage phenotype in NLPHL, but the neoplastic cells in CHL display an aberrant differentiation program with a characteristic CD15+, CD30+, and CD45– immunophenotype [1,2].
