An unusual complication related to acupuncture point catgut embedding treatment of obesity

Treatment of obesity by embedding catgut in acupuncture points has a satisfactory therapeutic effect in many patients. Even though results of its effectiveness are mixed, serious complications are rarely reported with this Chinese traditional therapy. Here an unusual complication of the treatment is reported: multiple tender subcutaneous nodules developed where the catgut was embedded over the lower abdomen and both medial thighs 1 month after treatment. Clinicians should be alert to this possible cause of a rather strange presenting physical sign.
