Composite lymphoma

ORPHA:168966Disease

Also called Composite Hodgkin and non-Hodgkin lymphoma

What it is

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.

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.
