Combined therapy of plantar warts with topical bleomycin and microneedling: a comparative controlled study‏.

Background: The aim of this study was to assess the efficacy of combination between microneedling with dermapen and topical bleomycin in the treatment of plantar warts in comparison with intralesional bleomycin and intralesional saline (placebo).Methods: Fifty-four patients were assigned into three groups, each containing 18 patients. The first group treated by micro-needling phenotype with topical bleomycin at 2 weeks interval, the second group received intralesional bleomycin at 3 weeks interval and the control group was intralesional saline for a maximum of four weeks.Results: Complete clearance of warts in 16 patients in the micro-needling group (88.9%) versus 15 patients (83.3%) in the intralesional bleomycin group versus one patient (5.6%) in the control group‏.Conclusions: Microneedling assisted topical bleomycin spraying seems to be a promising effective and noninvasive therapeutic modality for recalcitrant plantar warts that facilitates delivery and absorption of bleomycin into the lesion‏.
