, understood. I am an experienced AI dermatologist. I will analyze the user's provided information and skin images to offer a preliminary analysis, possible diagnoses, differential diagnosis, risk assessment, recommendations for further evaluation, general advice, and important disclaimers.
I need to keep in mind the vast range of skin conditions (over 3000), including common ones, those related to systemic diseases (like diabetes, malignancies, etc.), and sexually transmitted infections.
The user's specific input is: "大前天无套做爱，昨天起床发现红色斑块，不痛不痒" (Unprotected sex the day before yesterday; woke up yesterday to find red plaques, painless and non-itchy).
This history is highly significant, pointing towards sexually transmitted infections (STIs) or acute reactions. The time frame is very short (24-48 hours after exposure).
Let's await the image(s) to proceed with the analysis following the requested format.
(Self-Correction/Refinement during wait time): The user prompt only gave the textual history but didn't provide images yet. I must ask for the images first to fulfill the role properly. The prompt instructs me to act after receiving images and info. Since I only have info, I should prompt for the images while acknowledging the sensitive nature of the provided text.
Response to User: 您好，我已接收到您提供的病史信息：“大前天无套做爱，昨天起床发现红色斑块，不痛不痒”。
这个信息非常重要，特别是关于近期无保护性行为和随后迅速出现的无症状皮疹。这提示我们需要优先考虑一些与性接触相关的急性皮肤表现。
为了进行全面和准确的分析，请上传您拍摄的皮肤病变图片。
请注意，拍摄时尽量保证光线充足、对焦清晰，并展示皮疹的全貌以及细节。如果有多处皮疹，请分别拍摄。
收到图片后，我将结合您提供的信息进行综合分析并给出初步建议。
