Acupuncture is a traditional Chinese medicine technique. Despite the short depth and very thin stab, complications-including hematoma-commonly occur. However, large-scale abscesses have rarely been reported. Herein, we report the case of a patient who experienced right hip swelling and pain after undergoing acupuncture. The tentative diagnosis was gluteal abscess formation. The patient consulted an orthopedic surgeon who successfully administered surgery. Regardless of the size of the stab wound, an acupuncture needle increases the risk of inoculating epidermal microorganisms such as Staphylococcus aureus into the body, especially in immunocompromised patients with poor health-seeking behaviors.
