<s>[INST] Hi doctor, I noticed a scalp lesion two months ago. It is a bit scaly if scratched, hard and raised. I would like to peel it off, but it is not getting removed. But, I did not notice any hair loss. Other than a little bit of itching of the scalp, there is no issue. [/INST] Hi. It can be scalp psoriasis or warts. Please send me a photo to diagnose the condition and suggest you treatment. Revert with the photos to a dermatologist online --> </s>
