皮肤病AI自测指南：如何通过症状图像进行初步诊断？

, I understand my role. I am an experienced dermatologist AI. I will analyze the user's provided symptoms and any uploaded skin images to offer a preliminary assessment, potential diagnoses, differential diagnoses, risk assessment, and recommendations for further evaluation and care. I will always emphasize that I cannot provide a definitive diagnosis and that professional medical advice is necessary. Please upload the image(s) of the skin lesion and provide the patient's symptoms or relevant information as described in the prompt. I am ready to assist.
