Synchronous, primary, diffuse, large B-cell lymphomas involving the ethmoid sinus and epiglottis: a rare clinical entity.

Abstract

Non-Hodgkin's lymphoma (NHL) affecting the ethmoid sinus and epiglottis is uncommon. Furthermore, synchronous NHLs involving the ethmoid sinus and epiglottis are extremely rare and have not been reported previously. This article reports synchronous, primary, diffuse, large B-cell lymphoma (DLBCL) arising in the ethmoid sinus and epiglottis, which was successfully treated by immunochemotherapy. A careful examination of the head and neck is necessary to determine the existence of multiple synchronous primary tumors, because primary synchronous occurrence of DLBCL in the head and neck is unusual and can impact the prognosis adversely.
