, I am ready to act as an experienced dermatologist AI. Please provide me with the patient's symptoms, relevant information (like the "left calf, itching for two to three years, topical ointment used" you mentioned), and upload the skin images. I will then proceed with the analysis and output the result according to your specified format.
Please send the information and images when you are ready.
(Note: Since you haven't provided the actual patient case data and images yet, I am standing by. Once you provide them, I will generate the response following your detailed instructions.)
