Viral warts are one of the most prevalent dermatoses. The clinical picture varies from a single lesion with spontaneous cure to multiple recalcitrant lesions. Bleomycin sulfate is a cytotoxic action drug approved for the chemotherapeutic treatment of some malignancies. There are a number of studies that have been carried out during the last 45 years demonstrating its usefulness in dermatology, especially in intralesional therapy for viral warts, meaning it is an excellent option for lesions in difficult-to-handle topographies and for cases that do not respond to other approaches.
