Points in favor of myxoma included its female preponderance, potential to attain considerable size without noticeable signs and symptoms, association with missing tooth canine in this caseits predilection for premolar—first molar region in the maxilla and edsmoplastic ill -defined borders on radiographs. The lesion was treated via enucleation and curettage of the marginal bone and fenestration. Remnants of non-neoplastic bone often seem to remain in the tumor tissue.
Studies have been done to find whether the bone found is amelovlastoma bone or mature bone.
