Abstract
Richter transformation (RT) is a term used to refer to the development of an aggressive lymphoma, usually of diffuse large B-cell lymphoma type, in a patient with a history of chronic lymphocytic leukemia. It may present with heterogeneous manifestations, including the occurrence of tumors at extranodal sites. To date, only 6 cases of RT involving the oral and maxillofacial region have been reported. Here, we present 2 rare cases of lymphoma initially affecting the maxilla and the lower gingiva, respectively, of female patients with chronic lymphocytic leukemia and review the English language literature about RT manifesting in the oral and maxillofacial tissues.
