Multiple myeloma and malignant plasma cell neoplasms (C90)

Clinical Information for Multiple myeloma and malignant plasma cell neoplasms (C90)

Multiple Myeloma - A malignancy of mature PLASMA CELLS engaging in monoclonal immunoglobulin production. It is characterized by hyperglobulinemia, excess Bence-Jones proteins (free monoclonal IMMUNOGLOBULIN LIGHT CHAINS) in the urine, skeletal destruction, bone pain, and fractures. Other features include ANEMIA; HYPERCALCEMIA; and RENAL INSUFFICIENCY.

Smoldering Multiple Myeloma - An asymptomatic and slow-growing PLASMA CELL dyscrasia characterized by presence of MYELOMA PROTEINS and clonal bone marrow plasma cells without end-organ damage (e.g., renal impairment). It is distinguished from MONOCLONAL GAMMOPATHY OF UNDETERMINED SIGNIFICANCE by a much higher risk of progression to symptomatic MULTIPLE MYELOMA.

Interleukin-6 - A cytokine that stimulates the growth and differentiation of B-LYMPHOCYTES and is also a growth factor for HYBRIDOMAS and plasmacytomas. It is produced by many different cells including T-LYMPHOCYTES; MONOCYTES; and FIBROBLASTS.

Plasmacytoma - Any discrete, presumably solitary, mass of neoplastic PLASMA CELLS either in BONE MARROW or various extramedullary sites.

Instructional Notations

Type 1 Excludes Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
