, I understand. Please provide the patient's images and the specific description of their symptoms (in this case, "左小腿两到三年瘙痒明显外用药膏", which translates to "Left lower leg itching significantly for two to three years, using external ointment"). Once you provide the images, I will generate the response following the requested format.
Please upload the images of the skin condition on the left lower leg.
