Early clinical diagnosis of solitary plasmacytoma of the jaws: a case report with a six year follow-up.Int J Oral Maxillofac Surg. 2001 Dec; 30(6):558-60.IJ
The authors reported a case of a solitary mandibular plasmacytoma in a 53-year-old male Caucasian patient. The histological examination of the specimen was positive for a plasmacytoma with anaplastic appearance. Since the patient refused a demolitive surgical treatment, he was treated with a local radiation therapy of 4000 rads over a 20-day period and polychemotherapy with cyclophosphamide, prednisone and melphalan. Six years after starting radiation treatment the patient is free of recurrent primary disease and not affected by multiple localization. In conclusion, the solitary bone plasmacytoma represents an initial stage of the multiple myeloma rather than a distinct clinical pathology. Unfortunately, the diagnosis of the plasmacytoma is only rarely carried out in the early phases of the disease. The importance of the identification of the initial stage without a clear M component, as in the reported case, is self-evident, since the prognosis is related to the mass of plasmacytoma cells that are present at the time of the diagnosis. The purpose of this study is to report an extremely rare case of solitary bone plasmacytoma with a mandibular localization treated with radio- and polychemotherapy.
