Metal allergy is an uncommon problem during surgery. Among them, titanium allergy is said to be rare, but can lead to serious complications, such as palmoplantar pustulosis (PPP). A 69-year-old woman was admitted to our hospital with a chief complaint of chest pain. Coronary angiography showed severe coronary artery disease that required coronary artery bypass grafting (CABG). The patient had a history of orthopedic surgery for left distal radius fracture 2 years previously, which resulted in inflammation on the left arm and PPP. We suspected titanium allergy based on results of skin patch tests and use of titanium alloy in the previous orthopedic operation. The patient underwent CABG without use of permanent metallic material. As a result, her PPP disappeared. In this rare case, it is difficult to identify the exact cause of the improvement in PPP; thus, further studies are required to clarify the mechanism of remission.
