Patient's Query

Hello doctor,

I have a faint line on my finger from past ten days. I am attaching a picture of the same. What is it?

Answered by Dr. Suvash Sahu

Hi,

Welcome to icliniq.com.

I have read your concern and examined your picture (attachment removed to protect patient identity). There is nothing to worry, it is a single nail melanonychia. Nothing actively needs to be done.

Patient's Query

Thank you doctor,

Will melanonychia become cancerous later? I have got a few more faint lines in the same finger. It had a sudden onset ten days back. Will I get more lines like this? I am worried. What is the cause of this?

Answered by Dr. Suvash Sahu

Hi,

Welcome back to icliniq.com.

The causes of longitudinal melanonychia are many, it can be racial, inflammatory nail disorder like lichen planus, drugs like Zidovudine, Addison's disease, trauma, etc. A single band may represent nail matrix nevus. But in your case, it may be traumatic or inflammatory nail disease, so nothing seems to be worrying.

Patient's Query

Thank you doctor,

Can I get rid of this? Should I check it often for any changes?

Answered by Dr. Suvash Sahu

Hi,

Welcome back to icliniq.com.

Yes, you should check for any sudden change in color, size, or any abnormal growth. If it is due to any inflammatory or traumatic causes, it will resolve in a few months.

Same symptoms don't mean you have the same problem. Consult a doctor now!
