Talon noir (black heel, calcaneal petechiae) is a dermatological condition characterized by intraepidermal hemorrhage and exudation due to trauma.
Talon noir, more commonly occurs in young individuals involved in basketball, climbing or running. Talon noir occurs as a result of an injury that leads to the formation of intraepidermal hemorrhage and fluid accumulation on the soles.
As a result of the trauma (which often goes unnoticed by the patient), reddish, brown, or black asymptomatic plaque of various diameters appear on the sole or toes. When scraped with a scalpel, the color is seen in the peeling and it is removed from the skin. The main complaint and concern of patients is confusion with acral melanoma. Usually a thorough history helps in making the correct diagnosis.
Talon noir is usually diagnosed clinically supported by dermoscopy. In rare cases, histological examination may be required.

Approximately 4 weeks after avoiding sports activities + proper footwear selection, talon noir typically resolves on its own.
