I’m Seeking A Second Opinion On A Pigmented Patch On The Corner Of My Right Index Finger

Question : I’m seeking a second opinion on a pigmented patch on the corner of my right index finger.

It appeared about a year ago, not under the nail bed, but more on the skin adjacent to the nail.

It’s dark, scaly, and has not significantly changed in size or appearance since I noticed it.

I had been using Toppik hair fibers extensively around the time it appeared, applying it with that index finger, so I initially assumed it was staining.

I stopped using Toppik over 6 months ago, but the patch hasn’t faded.

A dermatologist prescribed steroid cream, which reduced the scaliness but did not affect pigmentation.

I’ve taken photos since January, and there’s no visible progression in the last 3 months, but I have no images from the earlier months to compare further.

It’s not painful, though I did feel mild tenderness when I started probing it — possibly due to anxiety and focus.

The dermatologist recommended a biopsy to rule out melanoma but said it appears to be a benign nevus and could be left alone if that’s confirmed.


I’ve looked at melanoma reference images, and this lesion doesn’t resemble what I’ve seen. Still, I’d like your professional evaluation before proceeding with the biopsy.
