If there is a mole on the foreskin, it is recommended to go to the hospital for further examination and symptomatic treatment. 1. If the mole is only an intradermal mole, which is only a local melanin deposition on the foreskin, and there is no obvious elevation when touched, no local enlargement and no surrounding redness or swelling, there is no need for special treatment and regular observation is sufficient, as it is mostly due to melanin deposition on the basal layer of the skin and will not cause any harm. The most common cause of melanoma is the presence of melanin in the basal layer of the skin, which does not cause any harm, but if the volume increases within a short period of time, the scope expands or is accompanied by redness and swelling, you can consider going to the hospital for local excision or using laser for local removal. 2. In this case, local excision is needed, together with the nearby foreskin, and after the operation, according to the results of the pathological examination, it is decided whether post-treatment is needed.
