A case of idiopathic purpura hyperglobulinemica in a 50-year-old woman was reported. She has had attacks of petechiae and flat, brown, slightly elevated papules on the lower extremities for 2 years. Besides these eruptions, on examination, she had the fine livedo reticularis on the thighs to patellar region. She complained of tendency to get tired soon after exercise in the M. gastrocunemius.

Marked increase of polyclonal IgG fraction in the serum protein was proved. The multiple myeloma was failed to be found. The cause of hypergammaglobulinemia could not be proved.
