Periungual wart is a kind of verruca vulgaris that occurs alongside or underlying the nails, which is challenging to treat and prone to recurrence, seriously affecting the quality of patients' life. We report a 6-year-old boy with periungual warts who had experienced various treatments with no improvement and even worsening. Therefore, we tried to treat the patient with local hyperthermia which uses a patented device that has an infrared emission source. The heat generated by infrared rays acts on the local skin surface. The mechanism of this therapy may be to establish a specific immune response against human papillomavirus-infected tissues, thereby facilitating the clearance of human papillomavirus at irradiated and non-irradiated sites. Local hyperthermia has the advantages of non-contact, safety, noninvasive, less pain, and so on. After 5 treatments, the irradiated periungual warts completely cleared after 2 weeks. The unirradiated sites were almost cured after 7 weeks. This case suggests that local thermotherapy has shown great advantages in the treatment of these refractory periungual warts and offers a new and effective therapy in patients with periungual warts.

Nail unit verruca is the most common nail tumor encountered in clinical practice and may be highly distressing to patients due to reduced functionality, cosmesis, and stigmatization. Subungual and periungual verrucae present a challenge for treatment compared to cutaneous warts of other sites and recurrence rates are high. The risk of spread to other skin and mucosal areas inherent to all warts may be increased given location on the fingertips.

Article Synopsis
- Warts, caused by human papillomavirus (HPV), can be treated using immunotherapy methods like the intralesional MMR vaccine and auto implantation to stimulate the immune system, leading to effective wart removal.
- A study involving 160 patients compared the two methods, with one group receiving the MMR vaccine and the other undergoing auto implantation.
- Results showed that the MMR vaccine had a higher success rate (86% excellent response) compared to auto implantation (71%), with both methods yielding low recurrence rates and minimal side effects.

Warts are a prevalent skin condition that can affect people of any age. They are caused by the human papillomavirus (HPV), a double-stranded DNA virus that can cause benign and malignant lesions and remains latent in the host cells, leading to recurrences. Although warts are benign and spontaneous clearance has been reported over the years, they often cause disfigurement, tend to koebnerize, and can be transmitted to others, making adequate and timely treatment important.

Subungual or periungual cutaneous warts are caused by the human papillomavirus (HPV). These lesions can be refractory to destructive therapy, necessitating the use of intralesional immunotherapies such as antigen. In this case report, we present a 23-year-old female who sustained distal fingertip soft tissue necrosis following intralesional injection of antigen for the treatment of a refractory subungual wart.

Warts are caused by human papillomavirus (HPV) infection and can involve multiple parts of skin and mucosa, of which periungual and subungual warts are the most difficult to treat. Periungual or subungual wart is verruca vulgaris growing around or under the fingernail, destroying and deforming the nail and nail bed. Currently, liquid nitrogen cryotherapy and CO laser are often used for the treatment.
