Hello doctor,

My dad is 65 years old and has lesions on his back. I have attached images for your reference. What could these be? He has a normal liver function test although his abdominal ultrasound shows fatty liver grade 2. He also has a normal lipid profile.



Welcome to icliniq.com.

I have viewed the images attached (attachment removed to protect patient identity). The dark spots are perhaps seborrheic keratosis which is a benign epidermal skin lesion. They are a part of aging and only of cosmetic concern. If desired, the seborrheic keratosis can be treated with electrofulguration. The white spots are IGH (idiopathic guttate hypomelanosis). The IGH is one of the skin changes seen in aging skins and requires no active intervention. I can also see some scratch marks which are linear excoriations.


Thank you doctor,

What are those long dark color macules like scratches all over? Are they skin lesions?



Welcome back to icliniq.com.

They are seborrheic keratosis lesions which are tan to brown color. They are macules which are slightly raised with a stuck-on appearance.
