Non-Hodgkins lymphoma

Distinct from Hodgkin lymphoma both morphologically and biologically, non-Hodgkin lymphoma (NHL) is characterized by the absence of Reed-Sternberg cells, can occur at any age, and usually presents as a localized or generalized lymphadenopathy associated with fever and weight loss. The clinical course varies according to the morphologic type. NHL is clinically classified as indolent, aggressive, or having a variable clinical course. NHL can be of B-or T-/NK-cell lineage.
