Alternating extra medullary plasmacytoma of maxilla.

Plasmatytomas of maxilla are rare lesions. Alternating plasmacytoma of maxilla is still rare. A case of maxillary extra medullary plasmacytoma is reported in a patient, who presented with same lesion in the opposite maxillary sinus within one year of initial presentation. On review of available literature we could not find bilateral medullary plasmacytoma involving both maxilla one after another.
