Composite lymphoma

Disease definition

A rare lymphoma characterized by the concurrent occurrence of two or more histologic types of lymphoma involving the same anatomic site. Composite lymphomas can be combinations of two non-Hodgkin lymphomas or of a non-Hodgkin and a Hodgkin lymphoma. In many cases, the tumors are clonally related. Clinical presentation and treatment are determined by the more aggressive component.
