What are the black dots in common warts?

The black dots found in common warts are typically formed due to ruptured capillaries within the wart, resulting in blood coagulation and oxidation. These black dots are actually pigmentation caused by iron ions in the blood during the oxidation process. They are generally located on the surface or deeper layers of the wart and represent a common manifestation of common warts. These black dots do not pose a direct threat to health, but they may affect a patient's appearance and self-confidence. When treating common warts, doctors usually select appropriate methods based on the size, location, and number of warts, such as topical medications, physical therapies, or surgical removal. During treatment, these black dots may gradually fade as the wart disappears. Patients need not worry excessively but should actively follow their doctor's treatment recommendations to promote recovery.
