Extramedullary plasmacytoma of gingiva and soft tissue in neck.

Plasmacytoma is a malignant disease that present either in bone marrow (medullary plasmacytoma), within the bone (solitary plasmacytoma of bone), or outside of bone, as the extramedullary plasmacytoma. Extramedullary plasmacytoma accounts for 3% of all plasma cell tumours and approximately 90% of extramedullary plasmacytomas affect the head and neck region commonly affecting the nasal cavity, paranasal sinuses, tonsillar fossa and oral cavity. Multiple extramedullary plasmacytoma is defined when there is more than one extramedullary tumour of clonal plasma cells and such presentations are extremely rare. We report such a rare case of multiple extramedullary plasmacytoma involving gingiva and neck. Here is a case report of a 65-year-old female patient presenting with extramedullary plasmacytoma of the gingiva and soft tissue in neck.
