IL6 and neoplasm: Right atrial myxoma (RAMs) may remain asymptomatic or appear with constitutional, obstructive, or embolic symptoms according to the size, fragility, mobility, and location of the tumor as well as body position and activity.[5,8] The nonspecific constitutional signs, which are present in 10% to 45% of patients with myxomas, are fatigue, fever, dyspnea, chronic anemia, weight loss, general arthralgia, and elevated interleukin-6, erythrocyte sedimentation rate, and c-reaction protein levels.[8] Therefore, the results of the laboratory tests may mimic those for rheumatic disorders.
