An odontogenic neoplasm that may be mistaken for an ameloblastoma but is of mixed tissue origin and considerably less aggressive is
1) A cementoblastoma
2) An odontogenic fibroma
3) A cementifying fibroma
4) An ameloblastic fibroma
Oral Pathology
Answer: 4
An ameloblastic fibroma is a benign odontogenic tumor that contains both epithelial and mesenchymal components, making it a mixed tissue neoplasm. While it can resemble an ameloblastoma histologically, it is generally less aggressive and has a better prognosis. Ameloblastic fibromas are often found in younger patients and can be treated effectively with surgical excision.
