Extramedullary Plasmacytoma of Left Buccal Mucosa – A Rare Case Presentation

Abstract Extramedullary plasmacytomas are uncommon, solitary soft tissue tumours that can be identified by histopathological analysis. They are caused by malignantly altered monoclonal plasma cell proliferation. Multiple myelomas, which are intimately linked to these lesions, should be ruled out in each of these instances by appropriate laboratory and radiographic examinations. This article reports a case of a 79-year-old man presented with a quickly expanding, painless swelling in the left cheek area. A diagnosis of solitary plasmacytoma was reached based on histological, radiological, and clinical data. It is crucial to diagnose extramedullary plasmacytomas as soon as possible. The treatment of choice is radiotherapy with or without adjuvant chemotherapy. Close patient monitoring is necessary following the conclusion of the therapeutic procedures since there is a chance that the condition will progress to multiple myeloma.
