Angiokeratoderma is usually a benign tumor and is a type of skin tumor. Angiokeratoderma is classified into five types: limited, papular, extremity, generalized, and scrotal. This disease is usually caused by the dilation of capillaries, or keratinization of the skin surface, etc. This disease usually occurs in adolescents, females or children, and this disease will cause the patient to have a small localized erythema, which is usually spreading in nature. When angiogranulomas are present, there are no obvious symptoms that require treatment. If pain or rapid growth occurs, it can be treated with laser, microwave or traditional surgery, or with medication such as phenytoin sodium under the direction of a doctor. If you find angiokeratoderma, you should go to the regular hospital in time and actively diagnose and treat it, so as not to delay the condition.
