Introduction

Prolonged friction on the skin may lead to pigmentation within the skin, which can further develop into dark-colored warts, presenting as black raised growths on the skin. If removal is desired, laser treatment can be used. The laser can precisely target the wart, vaporizing or carbonizing it to achieve the desired removal effect.

Generally, black raised warts may result from skin aging, long-term friction, common warts, filiform warts, genital warts, or other causes. The appropriate treatment should be selected based on the specific cause to achieve therapeutic effectiveness. It is recommended to seek medical attention promptly and follow medical advice for treatment. Details are as follows:

1. Skin aging: With increasing age, skin metabolism gradually slows down, which may lead to benign epidermal hyperplasia such as seborrheic keratosis, manifesting as black raised warts or flat papules. Generally, no special treatment is required. If they affect appearance, surgical excision may be performed.

2. Long-term friction: Prolonged skin friction may cause melanin deposition, resulting in the formation of black raised warts. If removal is desired, laser therapy can be used. Laser treatment precisely targets the wart, vaporizing or carbonizing it for effective removal.

3. Common warts: Caused by human papillomavirus (HPV) infection, these warts may appear as yellow-pea-sized or larger translucent papules, which may be brown, grayish, or flesh-colored. They gradually enlarge to form rough, raised nodules, appearing as black raised warts. As advised by a physician, topical medications such as tretinoin cream, salicylic acid cream, or fluorouracil cream may be used to promote keratinocyte exfoliation.

4. Filiform warts: Also caused by HPV infection, these warts lead to localized thickening and excessive keratinization of the skin, forming black raised growths that appear as slender, soft, thread-like projections. Under a doctor's guidance, antiviral medications such as imiquimod cream, cantharidin cream, or podophyllotoxin cream may be used for treatment.

5. Genital warts: Caused by HPV infection, these warts may appear on the skin surface and may be white, red, brown, or black in color. They typically occur around the genital or anal areas and may be accompanied by itching. As directed by a physician, medications such as transfer factor oral solution, acyclovir tablets, or valacyclovir hydrochloride tablets may be used for anti-infective treatment.

During treatment, patients should maintain healthy lifestyle and dietary habits. Avoid unhygienic sexual practices and excessive skin friction to prevent worsening of the condition or the development of new warts.
