This study aims to evaluate the efficacy and safety of intralesional injections of candida antigen, polidocanol sclerotherapy and combined candida antigen with polidocanol in treatment of patients with common warts.

Warts are benign proliferations of skin and mucosa caused by the human papillomavirus . Currently, more than 100 types of human papillomavirus have been identified, which is a non-enveloped double-stranded, circular, supercoiled DNA virus enclosed in an icosahedral capsid and comprising 72capsomers Immunotherapy in wart treatment is a type of biological therapy that uses substances to stimulate the immune system to help the body fight infected cells. This includes topical agents as imiquimod, sineacatechins, and Intralesional immunotherapy which become more preferred treatment line for several types of warts, several injectable agents have been examined such as vitamin D3, interferon alpha 2B and skin test antigens such as the candida antigen and purified protein derivatives or systemic immunotherapy as zinc, cimetidine.

Intralesional candida antigen has been successfully used in the treatment of warts with the potential advantages of promising efficacy, low cost, high safety profile, simple easy injection, association with distant response, absence of scarring and pigmentary changes and less pain than destructive therapies, and low or absent recurrence rates Treatments targeting and obliterating blood vessels such as pulsed dye laser and photodynamic therapy have been used in the treatment of common warts. Based on these observations, and the previous reports of the successful use of polidocanol in the treatment of various skin conditions with vascular components, the intralesional polidocanol therapy could be helpful in the treatment of common warts through the thrombotic occlusion and obliteration of blood vessels within the wart.

The complete and partial cure rates after intralesional polidocanol 3% injection in plantar warts were 60% and 25%, respectively
