We report two cases of inflammatory Pseudotumor of the maxillary sinus. Inflammatory pseudotumor of the paranasal sinus is a rare lesion, simulating a malignant tumor clinically. The first patient was a 40-year-old male complaining of trismus and left jaw pain. The other was a 41-year-old female complaining of trismus and right cheek swelling. CT scan and MRI findings revealed a mass of soft tissue density extending from the unilateral maxillary sinus to the infratemporal fossa with destruction of the maxillary bony wall in both patients. Histopathological examination of the tumors showed diffuse infiltration of plasma and other inflammatory cells, such as lymphocytes and histiocytes in the fibrous stroma. Immunohistochemical study demonstrated the polyclonal nature of the plasma cells. Because steroids were not effective in these cases, partial maxillectomy and coronoidectomy were performed under general anesthesia. We successfully treated trismus during the postoperative courses and there has been no regrowth of the masses.
