Phototherapy is an innovative treatment for acne vulgaris that is minimally invasive and simple. An 11-year-old boy consulted our hospital for right lower eyelid edema. Despite taking a thorough history of present illness, we were unable to make a preoperative diagnosis. After the surgery, the father informed us that his son had been diagnosed with acne vulgaris and had undergone xenon phototherapy at a dermatology clinic. A red bulge had appeared on his lower eyelid the next day that had gradually expanded. We diagnosed the patient as thermal skin lesion caused by phototherapy. Our findings suggest the importance of careful medical history taking for all medical examinations, as it may help physicians to provide patients with a definitive diagnosis and begin appropriate treatment. Moreover, paying close attention to adverse events post-administration is crucial.
