Cancer Types And The Cells They Originate From

Myeloma

When cancer originates in an individual's plasma cells, which are responsible for the production of infection-fighting antibodies, it is referred to as myeloma. Myeloma forms in specific plasma cells called plasma B cells when they are inside an individual's bone marrow. Myelomas are a type of plasma cell dyscrasia that can be classified into one of several forms. Multiple myelomas are the variation where numerous areas around the patient's body are affected and are the most common form of myeloma. Plasmacytoma is the form of myeloma characterized by a single focal site of myeloma cells in the body. Plasmacytoma often manifests as a tumor in a patient's skin, lung, bone, or muscle. Localized myeloma is a form similar to plasmacytoma, but it includes the added criteria that neighboring sites of the tumor have been exposed. Extramedullary myeloma is a classification of myeloma characterized by tissue involvement outside the patient's bone marrow, including the muscles, lungs, or skin.
