BACKGROUND Plasmacytomas are rare plasma cell tumours occurring consequent to monoclonal proliferation of plasma cells. They are divided into Solitary bone plasmacytoma, Extramedullary plasmacytoma (EMP) and Multiple myeloma. EMPs are commonly housed in the head and neck region with a predilection to the mucosa associated lymphoid tissue in the aerodigestive tract. The nasal cavity, paranasal sinuses, and nasopharynx are the most common sites. OBJECTIVE We describe our experience with this tumour owing to its clinical rarity and a different way of presentation. METHODS After complete surgical excision of a nasal mass presenting in a young male with features masquerading that of Juvenile Nasopharyngeal Angiofibroma, a diagnosis of plasma cell tumour was made on histopathological analysis which was confirmed using immunohistochemistry. Serum electrophoresis, urine Bence Jones proteins, complete skeletal survey were done to rule out any progression into multiple myeloma. Radiation therapy was given with 45 Gy in 25 fractions at 1.8 Gy per day, 5 days a week. RESULTS Followup after 2 years showed no recurrence locally as well as in regional nodes. CONCLUSION Given to the rarity of the tumour, undefined manner of presentation and a predominant prevalence in the head and neck region, every otolaryngologist should keep EMP in mind while considering sinonasal masses. A multidisciplinary approach with a combination of surgery and radiotherapy is found to benefit the patient significantly. A long term watch out for progression to MM is mandatory to commence early treatment and thus prolonged disease-free survival from the sam
