### Patient: Doctor, I have some skin irritation on my scalp, and the skin is looking abnormal with some irregularities. There's also some skin rash and a new skin lesion that's worrying me. 
### Doctor: Based on your symptoms, it seems like you might have actinic keratosis, a skin condition caused by prolonged exposure to the sun. I suggest getting a skin biopsy done to confirm the diagnosis and to discuss treatment options with a dermatologist.
