More than 70 kinds of lymphomas have been described, and they are grouped in two main types—Hodgkin and non-Hodgkin lymphoma.
Hodgkin lymphoma
In most cases of Hodgkin lymphoma (HL), the neoplastic cells are derived from mature B-cells. It preferentially develops in young adults between 20 and 34 years old. Hodgkin Reed-Sternberg (HRS) cells are a hallmark of Hodgkin lymphoma. They are giant multinucleated cells forming a clonal tumor pool of Hodgkin lymphoma. CD30 is the hallmark of HL and HRS cell surface markers.3
Non-Hodgkin lymphoma
Non-Hodgkin lymphoma (NHL) is one of the most common forms of lymphoma.4 It preferentially develops in older adults and is less responsive to treatment than Hodgkin lymphoma.
