[Plasmacellular neoplasms of the head and neck: clinical status and personal experience].

In this review, the authors examine the diagnostic, prognostic and therapeutic advances in clinical management of Solitary Plasmacytoma of bone, Extramedullary Plasmacytoma and their relationship to multiple myeloma. The clinical differences among these tumors are the subject of continued studies. Oral symptoms and signs of the neoplasias are relatively common. The literature is reviewed with respect to the prevalence of oral and maxillofacial manifestations and the presence of such manifestations as the first sign and/or symptom of disease. The case of a young adult patient, with a kappa-light-chain positive extramedullary plasmacytoma of the maxillary sinus is presented. The reported case illustrates the necessity of a multidisciplinary approach using relevant immuno-hematologic, radiographic and histologic investigations in the differential diagnosis of these tumors. Factors influencing the prognosis of these neoplastic lesions are also discussed.
