RESUMO
Warts are common viral infection of the skin, usually treated with destructive methods like electrocautery, cryotherapy or laser ablation. Topical vitamin D has been used to treat warts with variable success is to evaluate the efficacy of intralesional vitamin D3 injection in the treatment of common warts. Fifty patients were divided into two groups: 30 patients as cases group who received intralesional injection of 0.2 mL of vitamin D3 (300,000 IU) into the base of mother wart for two sessions and another 20 patients as a control group who were injected with normal saline solution. Standardized photographs were taken before the procedure, and 1 month and 3 months after the procedure. The degree of the response was classified into complete, partial, and no response. Complete clearance of the target injected warts occurred in 40% of patients in cases group while it occurred only in 5% of patients in control group (p ≤ .001) that was statistically significant. Intralesional injection of vitamin D3 may be considered a good and safe modality for the treatment of common warts.
