What are the clinical symptoms of warts?

Warts are skin surface growths caused by viral infections, and their clinical manifestations vary depending on the type. The clinical symptoms of warts are as follows: Warts typically present as raised papules or bumps on the skin surface, with a hard consistency and varying colors, such as normal skin color, light brown, grayish brown, brown, or dirty gray. Common warts frequently occur on the fingers, back of the hands, and edges of the feet. They are round or polygonal in shape, with rough surfaces, obvious keratosis, hard texture, and a tendency to bleed. Flat warts commonly develop on the face, back of the hands, and arms, presenting as flat papules the size of rice grains to green peas, slightly raised, with smooth surfaces and clear borders. Genital warts mainly affect moist areas of the genital and anal skin and mucous membranes. They initially appear as pale red papules, which gradually increase in size and number. The surfaces become uneven and rough, forming papillary or cauliflower-like growths. Molluscum contagiosum presents as hemispherical papules with a central white spot. These lesions gradually enlarge, become centrally depressed, have smooth surfaces, and can exude a white, cheese-like material. Therefore, individuals experiencing similar symptoms should seek medical attention promptly for accurate diagnosis and appropriate treatment.
