Solitary extramedullary plasmacytoma is a rare hematologic malignancy with nonspecific clinical symptoms and imaging findings. We present a case of this entity that arose in the nasal tract of a 50-year-old man. The tumor was removed surgically, and the patient showed no evidence of recurrence on follow-up. We review the clinical features, imaging and histopathologic findings, and treatment of this rare disease. It is essential for otolaryngologists and head and neck surgeons to be familiar with this entity because total excision and radiation therapy for plasmacytomas can be curative in patients who have no underlying overt plasma cell dyscrasias.
