Sensitivity to sternotomy wires may cause postoperative pruritus.

An eczematous eruption developed on the anterior chest of a 58-year-old woman with known nickel sensitivity after the insertion of nickel-containing sternotomy wires. Her wound was revised with removal of the wires to give immediate and sustained relief from the itch. The electron microscopy and parasternal biopsy histology demonstrating a sarcoidal reaction are discussed.
