Extramedullary plasmacytoma (EMP) is an uncommon neoplastic proliferation of monoclonal plasma cells. Despite having a better prognosis and lower conversion rate to multiple myeloma in comparison to solitary bone plasmacytoma, EMP diagnosis can be challenging. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) certainly has an established role in EMP diagnostic workup. Herein, we describe a rare case of nasal cavity EMP, highlighting 18F-FDG PET/CT potential in the detection of EMP occurring in atypical sites and providing a useful comparison in the differential diagnosis with other 18F-FDG avid nasal pathologies.

Abstract

Extramedullary plasmacytoma (EMP) is an uncommon neoplastic proliferation of monoclonal plasma cells. Despite having a better prognosis and lower conversion rate to multiple myeloma in comparison to solitary bone plasmacytoma, EMP diagnosis can be challenging. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) certainly has an established role in EMP diagnostic workup. Herein, we describe a rare case of nasal cavity EMP, highlighting 18F-FDG PET/CT potential in the detection of EMP occurring in atypical sites and providing a useful comparison in the differential diagnosis with other 18F-FDG avid nasal pathologies.
