Patients are usually asymptomatic and detected during routine radiographic examination. Management of OKC varies from conservative procedures like simple Enucleation and peripheral ostectomy to aggressive resection. More attention is given to new treatment protocols to form them simple and successful. 5 fluorouracil is an anti-metabolite used to treat basal cell carcinoma and other malignancies act by inhibiting thymidylate synthase an enzyme required for DNA synthesis causing cell death. This is a case report of a 40-year-old female patient with OKC treated with topical 5 fluorouracil after enucleation, has less morbidity minimal recurrence, and low cost.
