This case is reported because of the unusual pathologic picture in a primary tumor of the superior maxilla. Other cases of plasma cell tumors about the head and neck without skeletal involvement have been reported.1 So far as I am aware there are but few cases of such a tumor originating about the alveolar process.
Myelomas are considered most commonly to be tumors of the bone marrow which show multicentric foci of origin and produce certain characteristic roentgenologic changes in the bone involved. In addition, certain findings in the blood and urine are, as a rule, more or less commonly associated with the disease.
Histologically the new growths may vary in appearance from case to case and even from point to point within the same tumor. Study of numerous sections, however, almost invariably reveals collections of plasma-like cells with eccentric nuclei, which are the most significant and pertinent factor in
