A common primary bone malignancy in childhood and adolescence is Ewing’s sarcoma. Here we report multidisciplinary approach in the management of chronic hyperplastic candidiasis and xerostomia secondary to chemotherapy with vincristine, doxorubicin and cyclophosphamide (VDC) in a pediatric male patient with Ewing’s sarcoma of Ethmoid sinus. The initial diagnosed oral lesion was treated with topical clotrimazole 1%w/v for two weeks and Sucralfate 1g/10mL oral rinse for one month. Upon subsequent VDC chemotherapy cycle, the patient developed grade IV oral mucositis, severe neutropenia and associated oesophageal candidiasis. Treatment included combination of topical clotrimazole 1%w/v and Fluconazole 300mg/day (IV for 5 days and Tablet for 14 days). To prevent caries risk, pit and fissure sealants were applied and topical fluoride therapy was given; patient was encouraged to have frequent sips of water and prescribed kids xylitol gum for 15 days to minimize xerostomia. At 5-week follow up, reduction in burning sensation and resolution of white lesion was noted.
