[Primary non-Hodgkin's lymphoma of paranasal sinuses. Review of the literature and a case report].

A case of primary extranodal non-Hodgkin's lymphoma arising in paranasal sinuses, in an 89 year-old woman is reported. Histologically it was lymphoplasmacytoid, pleomorphic, diffuse, at intermediate grade of malignancy according to "Working formulation for clinical usage" in I EB stage. Complete resolution was obtained with polychemotherapy according to the scheme ProMACE-CytaBOM. After a wide review of the literature, the Authors emphasize incidence, prevalence, clinical symptoms (especially local), the different beginning points, prognostic and therapeutic factors, and the most frequent associations with other illnesses. Agreeing with other Authors, the necessity of using aggressive polychemotherapy is stressed, also in elderly patients, even if at the beginning of the illness.
