1. Introduction to Common Warts

Common warts are benign skin tumors caused by human papillomavirus infection. In traditional Chinese medicine, it is called "warts", "thousand-day sores", "dry tendon arrows", and commonly known as "thorn warts", "warts", etc. It is common in teenagers and is often seen on the fingers, back of hands, edges of feet, etc. Damage to the skin and mucous membranes is the main cause of infection. The initial symptoms are small hard papules that are grayish yellow or yellowish brown in color with a rough, keratinized surface. The disease develops slowly and can resolve naturally, or it can be treated with local medication and surgery.

2. Pathological Causes

The causative agent is human papillomavirus (HPV-1, 2, 3, 4, 7, 27, 28, 29). Damage to the skin and mucous membranes and abnormal cellular immune function are the direct factors for infection of this disease.

3. Symptoms and Signs

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.

2. Periungual warts and subungual warts: Common warts that occur around or under the nails of the fingers (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.

3. Special types

Filiform warts: 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.

Digital warts: A cluster of multiple jagged finger-like protrusions with keratinous tips occur on the same soft base. It often occurs on the scalp or between the toes, but can also occur on the face. There are usually several of them, which can last for a long time.
