Tongue extramedullary plasmacytoma (EMP) with regional lymph node metastases is a very rare pathology. Despite being a rare entity, extramedullary plasmacytoma should be considered a differential diagnosis in cases of a mass or ulcer in the tongue. A 60-year-old lady presents with an ulcerative lesion over the right lateral border of the tongue with dimensions 3.5 × 2 cm for one year. Initially, on histopathological examination, a possibility of plasma cell neoplasm was suspected; on further IHC, serum protein electrophoresis, and radiological investigations, a definite diagnosis of solitary EMP of the right lateral border of the tongue with regional nodal metastases was confirmed. The patient received radiotherapy for the primary disease along with the involved neck nodal sites.
