1. a plasma cell dyscrasia.
2. a discrete, presumably solitary, plasma cell tumor mass.

plas·ma·cy·to·ma

(plaz'mă-sī-tō'mă),
A discrete, presumably solitary mass of neoplastic plasma cells in bone or in one of various extramedullary sites; in humans, such lesions are probably the initial phase of developing plasma cell myeloma.

plasmacytoma

[plaz′məsītō′mə] pl. plasmacytomas, plasmacytomata,
a focal neoplasm containing plasma cells that may develop in the bone marrow, as in multiple myeloma, or outside the bone marrow, as in tumors of the viscera and the mucosa of the nasal, oral, and pharyngeal areas. Also called peripheral plasma cell myeloma, plasma cell tumor.

plasmacytoma (plaz´məsītō´mə),

n the primary soft tissue plasma cell tumors of the oral, pharyngeal, and nasal mucous membranes. The lesion consists of typical and atypical plasma cells, and its behavior is unpredictable. See also myeloma, solitary plasma cell and dyscrasia.
plasmacytoma, soft tissue,
n a primary plasma cell tumor of the nasal, pharyngeal, and oral mucosa that has no apparent primary bone involvement. The lesions are sessile or polypoid sessile masses in the mucous membrane. The majority remain localized, but metastases have been reported.

plasmacytoma

any focal neoplasm of plasmacytes, including those of multiple myeloma (immunoblastic sarcoma). Isolated plasmacytomas may occur outside the bone marrow (extramedullary plasmacytomas), affecting such tissues as the nasal, oral, pharyngeal and gastrointestinal mucosa and other viscera; called also plasma cell tumor.
