Radiographic findings included a sinus mass with bony invasion and expansion. The findings were radiographically indistinguishable from common malignant neoplasms and aggressive infectious processes. Malignant plasmacytoma should be considered in the differential diagnosis of invasive paranasal sinus masses in chronically immunosuppressed patients.
