an oral plasmacytoid mass: the result of a malcontrolled multiple myeloma

introduction: multiple myeloma is a neoplasm of monoclonal plasmacells which may cause oral manifestations. we report a 50-year-old man with a mass burned out of a post extraction socket. he had recived an eight month period of chemotherapy and was supposed to be ready for hematopoetic stem cell transplantation. after clinical and histopathological examinations, the mass was diagnosed as a plasmacytoid cell proliferation. as the oral manifestations are an indicator of poorly controlled disease, the patient was refered to change his chemotherapeutic regimen. conclusion: it seems that a team work, including oral medicine specialists may be a valuable opportunity in monitoring and promoting the quality of therapy.
