Septal plasmacytoma: Dilemma of diagnosis.

Plasmacytomas are malignant tumours characterised by abnormal monoclonal proliferation of plasma cells. They may be osseous or may arise from soft tissues. Extramedullary plasmacytoma (EMP) accounts for only 1% of all head and neck malignancies. Septal plasmacytomas are extremely rare. Here, we report a case of an 80-year-old male patient with alocalised plasmacytoma arising from the nasal septum, which was resected endoscopically, with post-op radiotherapy and no recurrence in 1 year of follow-up. A multidisciplinary approach is required for the optimal diagnosis and management. It is essential to exclude any systemic involvement before arriving at a diagnosis of solitary plasmacytoma. Depending on lesion resectability, a combined therapy is the treatment of choice.
