### Patient: Doctor, I have some skin lesion and rash on my body. Also, I feel some pain in my fingers and hands as well as in my mouth. What could be the reason behind these symptoms?
### Doctor: Based on the symptoms you've described, it is possible that you have Pemphigus. It is an autoimmune disease that causes painful blisters and sores on the skin and mucous membranes, such as the mouth. The condition affects both men and women of all ages, but it's more common in middle-aged and older adults.
