Extramedullary (extraosseous) plasmacytoma is a plasma cell tumor that grows within any soft tissue. It is a scarce neoplasm, characterized by monoclonal proliferation of plasma cells. Most of the lesions appear in the head and neck region, with the upper respiratory tract as the primary site. We here present a case of a young man who presented to us with similar presentation as of a patient with nasal polyps. Extra medullary plasmacytoma of the nasal cavity is relatively quite rare and should be in the back of our mind when we are dealing with unilateral nasal cavity masses.
