Talon noir is a dermatologic finding constituting an intraepidermal hemorrhage on a foot.
[1] Appearing as an asymmetrical brown-black epidermal lesion, it occurs in runners and hikers as a result of repeated trauma to the foot.
[2][1] Its onset is thus acute.
Talon noir can cause concern as it resembles acral melanoma, though unlike acral melanoma, talon noir is benign and self-limiting.
