Bleomycin Intralesional Injections of Cystic Hygromas

Plain-language summary

Thirty pediatric patients with cystic hygromas participated in this study. The cystic fluid was aspirated from the cystic hygroma, and the lesion was simultaneously injected with Bleomycin. Then, the lesion was re-injected at 4-week intervals until satisfactory results were obtained. Clinical response was evaluated as complete response (\> 90% reduction of lesion size), marked improvement (\>70% reduction of lesion size), moderate improvement (40 - 70% reduction of lesion size), slight improvement (\< 40%), and no response (\< 10% reduction of lesion size).
