Common Warts

Common warts are rough, benign skin growths caused by certain strains of human papillomavirus. They often appear on the fingers, hands, knees or around the nails. ^[1][2]

What is Common warts?

The virus enters through tiny breaks in the skin and stimulates extra skin growth. Warts can spread to nearby skin or to other people through direct or indirect contact, although not every exposure leads to infection. ^[1][3]

What are the symptoms and what causes it?

Typical warts are firm, rough and raised, sometimes with tiny dark dots from clotted capillaries. They are more common when skin is frequently irritated, bitten or shaved. ^[1][2][3]

How is it diagnosed?

Diagnosis is usually clinical. Most cases do not need biopsy unless the lesion looks unusual, bleeds easily, grows rapidly or does not respond as expected. ^[1][2]

What are the treatment options?

Treatment may include salicylic acid, freezing therapy or other office-based methods. Some warts go away on their own, but treatment may be preferred when they are painful, spreading or cosmetically bothersome. ^[1][2][4]

Possible complications and when to seek medical care

Common warts are usually not dangerous, but painful lesions, uncertain diagnosis or rapid changes should be assessed. Genital lesions are a different category and need separate evaluation. ^[1][2][3]

What may help in daily life?

Avoid picking or biting warts and avoid sharing tools such as nail clippers or pumice stones. ^[2][3]

Common mistakes during follow-up

A common mistake is repeatedly cutting or scratching a wart, which can spread the virus locally. ^[2][4]
