We describe 2 cases of children with malignant disease who developed severe mucositis with perineal necrotizing fasciitis during severe neutropenia after chemotherapy. Treatment with topical negative pressure therapy with silver foam dressing, together with large spectrum antibiotics, resolved the problem with complete closure of the wound after 30 and 36 days of treatment, respectively.
