Talon noir

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.^[1][2]
