Warts
Warts are benign skin growths caused by infection with the human papillomavirus (HPV). HPV infects the top layer of skin, causing the cells to grow rapidly, leading to the formation of a raised, rough, and often painless bump on the skin. Warts can occur anywhere on the body but are most commonly found on the hands, fingers, feet, and face.
There are several types of warts, each caused by different strains of HPV:
- Common warts (verruca vulgaris): These warts typically appear as small, rough bumps with a grainy texture on the hands, fingers, or around the nails. They may have black dots (clotted blood vessels) in the center.
- Plantar warts: These warts develop on the soles of the feet, often in areas subjected to pressure or friction. Plantar warts may appear flattened due to pressure from walking and can cause pain or discomfort when walking.
- Flat warts (verruca plana): These warts are small, smooth, and flat-topped, often appearing in clusters on the face, neck, hands, or legs. They may be flesh-colored, pink, or light brown.
- Filiform warts: These warts have a long, narrow, finger-like appearance and often develop around the mouth, nose, or eyes. They may also occur on the neck or under the chin.
