Resumo

Black heel (calcaneal petechiae) is an asymptomatic lesion caused by trauma. It is benign and self-limited, and usually occurs in teenagers and young athletes. In most cases, it is located on the posterior or posterolateral part of one or both heels. It is the clinical expression of a haemorrhage initially located in the dermis that is eliminated through the epidermis (corneal layer). It tends to disappear completely when the caus¬al activity stops. Treatment is not compulsory due to its asymp¬tomatic nature and its spontaneous resolution. However, differential diagnosis is very important to rule out malignant melanoma. The location of the injury, its bilaterality, the absence of symptoms and its development in a young sportsman are important diagnostic clues that can lead to the correct diagnosis, thus avoiding an unnecessary skin biopsy.
