Document Summary
Plasmacytoma is a buildup of abnormal plasma cells in either bone or soft tissue. A single (solitary) plasmacytoma is where there is one area of plasmacytoma, some people have more than one and that is called multiple solitary plasmacytoma. Single and multiple plasmacytomas can grow outside the bone marrow, for example in head and neck areas. A plasmacytoma that develops outside the bone marrow is called soft tissue plasmacytoma. Solitary plasmacytoma can be divided into 2 groups according to location: Solitary bone plasmacytoma (sbp)- plasmacytoma of the skeletal system. Extra medullary plasmacytoma (emp) is tumours formed in soft tissue. Sbp accounts for less than 5% of all myeloma cases. Emp accounts for 3% of all myeloma cases. 3:1 men: women ratio for emp o. It usually occurs in older patients aged 40-80 years of age o. The median age is 55 years old, which is 10 years younger than patients with multiple myeloma. Family history of multiple myeloma or plasmacytoma.
