Black areas on the heel in a teenager.
The same condition may occur on the fingers.
TALON NOIR
In Talon Noir (TN), aka black heel, blood appears as black dots on the heel.
- It is induced by vigorous exercise, e.g. basketball, volleyball, which through sheering forces, causes extravasation of blood.
- A similar finding called pigmented palmar petechie may be found on the palms.
Clinical
Tiny pinpoint black dots coalescing into a plaque appear on the lateral edges of the heel. Bilateral lesions are common. These changes may occur on the palms as well.
Treatment
No treatment is needed. The main differential is warts and rarely melanoma. The lesions will be shed over several weeks.
