Heel contusions

　　1, Etiology

　　The etiology of this disease is unclear, and it is generally believed to be related to local friction or injury.

　　2, Pathogenesis

　　The pathogenesis is not very clear, and it may be due to the rupture of superficial capillaries in the dermis, with hemoglobin metabolized and excreted through the epidermis and stratum corneum, causing changes similar to hyperpigmentation of the skin. It may also be a part of the symptoms of juvenile thrombocytopenic purpura.

　　1, Skin hyperpigmentation:Changes in hormones within the body can cause melanin to deposit in the skin, leading to skin hyperpigmentation (such as Addison's disease, pregnancy, or oral contraceptives). Skin hyperpigmentation can also be caused by the deposition of iron and silver in the skin tissue.

　　2, Thrombocytopenic purpura:Clinical manifestations mainly include skin and mucous membrane bleeding or internal organ bleeding, and severe cases may have bleeding in other parts such as nosebleeds, gum bleeding, excessive menstrual bleeding in women, or severe vomiting of blood, coughing up blood, hematochezia, and hematuria.

　　Commonly occurs in adolescents, especially in ball players, and often occurs on the back or sides of one or both heels, occasionally seen at the distal end of the metatarsal or several toes, often occurring suddenly, with lesions being clustered blue or black spots that do not fade when pressed, with unclear boundaries, which can merge with each other, usually without自觉 symptoms, and may be accompanied by excessive sweating.

　　The skin damage caused by this disease is closely related to excessive friction of the skin, and it often occurs in active adolescents, so the focus of clinical prevention should be on the etiology. When exercising, comfortable sports shoes should be worn to avoid severe friction and trauma. If necessary, exercise can be temporarily suspended to reduce recurrence, which can significantly reduce the incidence of heel contusions. For patients who already have this disease, active treatment should be carried out to reduce the occurrence of complications.

　　Histopathology:Hyperkeratosis, saccular dilation of sweat ducts, in which red blood cells or amorphous yellow-brown round aggregates can be seen; Perls blue staining is negative, and the peroxidase and biphenyl tests are positive, indicating that it originates from hemoglobin, with extravasation of red blood cells in the dermal papillary layer.

　　1. Treatment

　　This disease is caused by persistent friction of the skin and mucosa, so in general, no treatment is required for this disease.
