Introduction

In general, a plantar wart on the sole of the foot is usually caused by human papillomavirus (HPV) infection. Under medical guidance, patients may choose treatments such as laser therapy, electrocautery, cryotherapy, medication, or surgical intervention to improve the condition. In summary, if the above issues occur, it is recommended to promptly visit a reputable hospital for standardized treatment to prevent recurrence of the condition.

Generally, a plantar wart on the sole of the foot is usually caused by infection with the human papillomavirus (HPV). Under medical guidance, patients may choose from treatments such as laser therapy, electrocautery, cryotherapy, medication, or surgical intervention to improve the condition. Specific options are analyzed below:

1. Laser Therapy

Laser treatment for plantar warts involves using a high-energy light beam generated by a laser device to destroy affected tissue. The laser energy produces heat in the affected area, damaging proteins, cell walls, and capillaries within the lesion, ultimately leading to ulceration and necrosis of the wart.

2. Electrocautery Therapy

Electrocautery therapy introduces high-frequency electrical current into the plantar wart tissue, generating heat to destroy the abnormal tissue. During the procedure, the electrode directly contacts the wart, and the thermal energy produced through electrical conduction damages the cellular structure and blood supply of the lesion.

3. Cryotherapy

Cryotherapy, also known as liquid nitrogen therapy, involves applying extremely cold liquid nitrogen directly to the affected wart tissue to freeze and destroy abnormal cells. This rapid cooling damages cell membranes and capillaries, resulting in tissue necrosis.

4. Medication

For smaller plantar warts, topical medications such as compound salicylic acid solution, imiquimod cream, or fluorouracil cream may be used under medical supervision to improve the condition.

5. Surgical Treatment

If the warts on the sole are large in size or numerous, and other treatments have proven ineffective, surgical excision at a reputable medical facility may be considered to remove the lesions directly.

In summary, if the above issues occur, it is recommended to promptly visit a qualified medical institution for proper diagnosis and standardized treatment to prevent recurrence.

It is recommended to seek medical attention promptly and undergo treatment under a doctor's guidance. In daily life, one should avoid sharing slippers, foot basins, or other personal items with others; maintain good foot ventilation, avoid prolonged foot perspiration; and maintain a balanced diet and control blood sugar levels.
