Plasmacytoma of the maxilla: report of case.

A case report of plasma cell tumor of the maxilla has been reported. In addition, the characteristics of both the solitary lesion and multiple myeloma are presented to compare and contrast the two lesions. We realize that the follow-up period to date has not been sufficient to justify the final diagnosis of solitary plasma cell tumor, even though laboratory data thus far have not indicated dissemination. The patient's condition may or may not progress into the disseminated stage, but this will be determined by time.
