Abstract

A 52-year-old patients suffering from nasal stuffiness had necrotic, ulcerative polypoid mass in both nasal cavity. CT and MRI revealed bilateral polypoid mass with bony invasion in left maxillary anterior and posterior wall, left pterygopalatine fossa and right central skull base. The patient was diagnosed as plasmacytoma by histologic examination. To rule out multiple myeloma, several additive studies such as bone scan, bone marrow biopsy, urine Bence-Jons protein, serum protein electrophoresis, peripheral blood smear were performed and all results were negative. The patient was transferred to department of hemato-oncology and got 2 times of chemotherapy consisting of cyclophosphamide and dexamethasone and radiotherapy (5400 cGy / 30 fractionation). A month after the completion of chemoradiotherapy, the sized of mass decreased significantly without evidence of progression.
