Black heel, talon noir or calcaneal petechiae?
Urbina F, León L, Sudy E
Australas J Dermatol. 2008 Aug;49(3):148-51

We describe a series of six patients with superficial cutaneous haemorrhages of the feet, including a classical case of black heel (talon noir) and other similar cases with diverse clinical presentations that do not match the typical description of that process. The main differences lay in production mechanism, morphology and location. The causes of these 'atypical' lesions were: burns with hot sand, friction against the rough edge of a swimming pool, wearing new shoes, jogging, or pricking a blister with a needle. Clinically, they consisted of isolated or multiple, small, large or linear, brown or black lesions located in areas that did not include the convex part of the heel, in which talon noir usually appears; on the contrary, the lesions affected the back third of the soles, the toes, periungual fold and plantar arch. As the presence of blood in the horny layer was a common final factor in all these cases, a better name for this process would be 'post-traumatic cutaneous intracorneal blood' to describe black heel and its diverse clinical presentations.

Talon Noir in a Young Baseball Player: A Case Report

J Pediatr Health Care. 2020 Dec 10;S0891-5245

When evaluating pediatric patients with hyperpigmented lesions on the plantar aspect of the feet, the differential diagnosis should include talon noir, acral melanoma, and verruca with thrombosis. Talon noir are asymptomatic brown-black pigmented macules formed by intraepidermal hemorrhages of the feet caused by shear-force injury. Spontaneous resolution of talon noir typically occurs within 2-3 weeks. Clinicians should ensure that their patients who participate in sports have appropriately fitting shoes, which may prevent these lesions from occurring. This case report highlights a unique case of talon noir occurring in a young baseball player with an atypical distribution of plantar macules.

Talon Noir: A Case Report and Literature Review
Sampa Choudhury , Ashish Mandal
Cureus. 2023 Mar 8;15(3):e35905.

Talon noir is an asymptomatic, self-limiting, dermatological condition that is most commonly seen in young athletes and mountain climbers. Histologically, the characteristic findings are intraepidermal hemorrhage and fluid collection due to shearing forces. Here, we report an interesting case in an elderly female, which mimicked acral melanoma clinically and alerted us to do a biopsy for confirmation.
