a result of excess synthesis of such chains or from mutant
cells that make only such chains. Both mechanisms appear
operative, and more than 50% of patients with multiple
myeloma, a plasma cell neoplasm, have B–J proteinuria.
The highest frequency of B–J excretion is seen in IgD
myeloma; the lowest is seen in IgG myeloma. The daily
amount excreted parallels the severity of the disease. These
proteins are secreted mostly as dimers and show unusual
heat solubility properties. They precipitate at temperatures
between 40 and 60˚C and redissolve again near 100˚C.
With proper pH control and salt concentration, precipitation
may detect levels as low as 30 mg/100 mL of urine. Better
identification is by protein electrophoresis.
benign
A nonmalignant neoplasm or a mild clinical illness.
benign lymphadenopathy
Lymph node enlargement that is not associated with
malignant neoplasms. Histologic types of benign
lymphadenopathy include nodular, granulomatous,
sinusoidal, paracortical, diffuse or obliterative, mixed,

and depleted; clinical states are associated with each
histologic pattern.
benign lymphoepithelial lesion
Autoimmune lesion in lacrimal and salivary glands associated
with Sjögren’s syndrome. Myoepithelial cell aggregates
together with extensive lymphocyte infiltration are present.
benign monoclonal gammopathy
A paraproteinemia that occurs in normal healthy subjects
who develop the serum changes characteristic of myeloma
(i.e., a myeloma protein-type immunoglobulin spike on electrophoresis).
They have none of the clinical signs and symptoms
of multiple myeloma and their prognosis is excellent.
benign tumor
An abnormal proliferation of cells that leads to a growth that
is localized and contained within epithelial barriers. It does
not usually lead to death, in contrast to a malignant tumor.
