I have light colored vertical lines in my finger nails. Can you help me out?

Question

Hi doctor,

I have recently noticed some light colored vertical lines in my thumb and index finger nails. I have attached the photos for your reference. When I searched on the internet, I found very disturbing things including skin cancer. I have hypothyroidism and chronic depression. I am on Bupron 300 and Thyroxin 100. By looking at the pictures, can you help me out?

Please help.

Hi,

Welcome to icliniq.com.

You are having longitudinal melanonychia. It is also one of the signs of hypothyroidism. You might be concerned about melanoma, but melanoma does not present like this.

I hope this helps.

Thank you.
