Hodgkin's Lymphoma
Hodgkin Lymphoma (HL) arises from germinal center or post-germinal center B cells. HL has a unique cellular composition, containing a minority of neoplastic cells (Reed-Sternberg cells and their variants) in an inflammatory background.
Reed-Sternberg cell is a characteristic feature of HL.
Clinical Presentation:
 • Lymphadenopathy - painless, firm cervical or supraclavicular node, Anterior mediastinal mass/ adenopathy
 • Cough, Dyspnea, fever, Night sweats, Weight loss, Anaemia, Pruritis, Erythema nodosum, Immune hemolytic anemia, Pain in LN on alcohol ingestion, B symptoms in 1/3 of pts
Classification:
 • Classical HL - (90-95% of cases). The tumor cells in this group are derived from germinal center B cells, but typically fail to express many of the genes and gene products that define normal germinal center B cells.  Classical HL is further divided into the following subtypes:
 • Nodular sclerosis classical HL (NSHL) - (most common)
 • Mixed cellularity classical HL (MCHL)
 • Lymphocyte rich classical HL (LRHL)
 • Lymphocyte depleted classical HL (LDHL)
 • Nodular lymphocyte predominant HL - The tumor cells in this subtype retain the immunophenotypic features of germinal center B cells.
