Black Heel and Palm
Black heel and palm, also known as Calcaneal Petechiae, Talon Noir, or Post-traumatic Punctate Hemorrhage, is a benign, self-limiting condition characterized by dark, macular lesions on the palms or soles.
Pronunciation
Black heel and palm: /blæk hiːl ænd pɑːm/
Etymology
The term "black heel and palm" is derived from the appearance of the condition, with "black" referring to the color of the lesions, and "heel and palm" indicating the common sites of occurrence.
Symptoms
The primary symptom of black heel and palm is the presence of small, dark spots on the soles of the feet or palms of the hands. These spots may be singular or multiple, and are typically painless.
Causes
Black heel and palm is thought to be caused by trauma or pressure to the skin, resulting in hemorrhage into the stratum corneum. It is commonly seen in athletes and individuals who participate in high-impact activities.
Diagnosis
Diagnosis of black heel and palm is typically made based on clinical presentation. In some cases, a skin biopsy may be performed to rule out other conditions.
Treatment
As black heel and palm is a self-limiting condition, treatment is typically not necessary. In some cases, reassurance and education about the benign nature of the condition may be provided.
