A plasmacytoma is a type of tumor that arises from plasma cells, which are a form of white blood cell responsible for producing antibodies. These tumors can occur in bone (solitary plasmacytoma of bone) or in soft tissue (extramedullary plasmacytoma). While plasmacytomas are considered a localized form of multiple myeloma, they can potentially progress to more widespread disease if not treated. Diagnosis typically involves imaging studies, biopsy, and evaluation of bone marrow involvement.
