Sweat stoma is a benign tumor originating from the ducts of the sweat glands within the epidermis, also known as sweat gland sweat stoma. It is usually solitary and occurs mainly on the lateral metatarsal margins of the feet, but also on the palms of the hands, thighs, popliteal fossa, and the dorsal surface of the chest. The incidence rate of the disease is balanced between men and women, and it is more common in people over 40 years old. In the early stages of the disease, the main manifestation is a nodule on the surface of the skin, which is usually painless. As the size of the nodule increases, some of the compressed nodules may develop erosions, bleeding and ulcers. Sweat gland stomatoma is mainly treated by surgery, and drug treatment is generally ineffective. Sweat gland stomatomas that have already appeared should always be surgically removed by a professional doctor.
