The difference between common warts and flat warts

Common warts and flat warts are common diseases. Common warts often occur on the fingers, back of hands and other gradually marginal areas. Generally, they will show large-area skin loss in the onset stage. Flat warts will appear on many teenagers and are also more common in adults. They will cause some oval lentil-sized bumps and bumps to appear on the skin surface.

Symptoms and signs of common warts 1. Prevalent sites: Mostly seen on fingers, back of hands, edges of feet, etc. It can also occur anywhere on the body surface, even the nostrils, tongue, ear canal, inner lips, and eyelid margins. Extensive cases can affect most of the limbs.

2. Clinical symptoms

(1) General manifestations: In the early stage of the disease, it manifests as hard, small papules protruding from the skin surface, which are grayish yellow, grayish white, yellowish brown or light yellow, with a rough and keratinized surface. The number is uncertain. At first there is usually only one, but later the number may increase to several or even dozens. As the disease progresses, the lesions may increase in size and become patchy (Figure 1).

(2) Periungual warts and subungual warts: Common warts that occur around or under the nails of the fingers or toes are called periungual warts or subungual warts. Its root is often located inside the nail contour, appearing as simple keratosis. Only when it invades the skin will typical wart-like lesions appear. If it spreads under the nail and lifts up the nail, it will disrupt the growth of the nail and easily cause cracks, pain and secondary infection.

Filiform warts (verruea filiformis): They often occur on the eyelids, neck, chin, etc. They are single, soft, filamentous protrusions, usually no longer than 1 cm, with normal skin color or brown-gray. Generally no symptoms.
