### Patient: Doctor, I have a lump on my finger and there's an abnormal-looking skin over it. Also, I have some skin moles on my hand. What could be causing this? 
### Doctor: Based on your symptoms, it seems like you might have a sebaceous cyst. It's a small, benign cyst filled with keratin that can appear on different parts of the body, including hands or fingers. Would you like me to take a closer look and confirm the diagnosis?
