A 51-year-old man was referred to our department with a 2-day history of epigastric tenderness. He also noticed a mass in the same area. There was no spontaneous pain nor pain induced by posture or movement. His past medical history and medication were unremarkable. Physical examination showed that a firm mass of about 1 cm x 1 cm in size with tenderness was palpated in the epigastric region. Carnett’s sign was positive. This suggested abdominal wall pain, and the mass was consistent with the xiphoid process, suggesting xiphodynia.
