A small benign growth (as in the lungs or uterus) usually made of smooth muscle cells.
++
Metabolic disarray, often accompanied by acute kidney injury, in patients whose cancers are rapidly killed, (as when lymphoproliferative malignancies are treated with chemotherapy). Each dying malignant cell releases potassium, phosphates and uric acids into the bloodstream. The effect of cellular destruction produces toxic or potentially fatal concentrations of these chemicals, or severe hypocalcemia. The syndrome may be prevented by making sure certain chemotherapy patients are massively hydrated before treatment and by administering drugs, such as allopurinol or rasburicase, that inhibit or degrade uric acid. Hemodialysis is sometimes required.

tumor necrosis factor receptor-associated periodic syndrome

ABBR: TRAPS. A rare, dominantly inherited autoinflammatory disorder marked by bouts of abdominal pain, fever, myalgia and arthralgia, pleurisy, and conjunctivitis. It is caused by a mutation in a cell receptor for tumor necrosis factor. SEE: tumor necrosis factor.
