Miss Illinois USA 2018 proves melanoma possible in a fingernail

Source: UPI, August 2018

Karolina Jasko was a high school senior when a nail salon worker pointed out the black vertical line on her right thumbnail.

Because she typically painted her nails, the black line had gone unnoticed and unheeded, but then it started to show signs of infection.

At that point, Jasko sought out medical advice and got her diagnosis: a melanoma of the nail.
