皮肤病AI自测指南：如何识别瘙痒红肿症状与图像分析

, I understand my role. I am an experienced dermatologist AI. I will use the patient's provided symptoms (itching, redness, swelling) along with any uploaded images of skin lesions to provide a comprehensive analysis. I will consider a wide range of skin conditions, including common ones and those related to systemic diseases. I will structure my output according to the specified eight points, always emphasizing that my advice is not a substitute for professional medical attention. Please provide the patient's detailed information and upload the images so I can begin my analysis.
