Full Text PDF [1853K] Abstracts References(32) The occurrence of ameloblastic fibro-odontoma (AFO) in the oral region is unusual and accounts for 1-3% of all odontogenic tumors. AFO presents mixed radiopaque patterns within the lesion with diverse findings; therefore, it is important to compare this tumor with other odontogenic tumors that ... common location for complex odontoma, compound odontomas are mostly found in the anterior maxilla (6). This case report presents an unusual case of compound odontoma in the anterior mandible of a nine-year-old child. Case Report A healthy nine-year-old girl reported to … Summary: Calcifying epithelial odontogenic tumors and calcifying odontogenic cysts are rare, benign odontogenic tumors. We report two cases of an exceptional combination of these tumors with either an ameloblastic fibroodontoma or an odontoma.
Ameloblastic fibro-odontoma is a rare benign mixed odontogenic tumor with histologic characteristics of ameloblastic fibroma and complex odontoma. As with ameloblastic fibroma, it may be asymptomatic or found because of painless swelling and delayed eruption of associated tooth.

A 2-year-old Morgan stallion was brought to the attention The term “ameloblastic fibro-odontoma” represents a histological combination of AF and complex odontoma. Cahn and Blum (1952) postulated that histologically AF least differentiated tumor initially and develops later into a moderately differentiated form, AFO, and finally into complex odontoma. 6.

The odontogenic epithelial component was arranged in thin plexiform ribbons with globular protuberances and irregular follicle-like aggregates (Fig. 1). The epithelial cells were gen-erally columnar with anti-basilar nuclei.
Ameloblastic fibro-odontoma is one such tumor. Though the WHO 2017 Classification of Head and Neck tumors continues to support this hypothesis, it is clear, with more than 215 case reports, that it is a tumor that does not feature in the continuum of the spectrum of ameloblastic fibroma ending with ameloblastic fibro-odontoma and odontoma. developing tooth in the compound odontoma. An amelo-blastic odontoma contains abundant epithelium in addition to the dental tissues [8, 9, 11]. The literature contains several reports of odontogenic neoplasms in rats. These include ameloblastic odontoma (odontoameloblastoma) [1, 5, 7], odontogenic fibroma  and ameloblastoma [4, 10]. Ameloblastic fibro‑odontoma(AFO) is a rare odontogenic tumor. Initially believed to be a lesion similar to ameloblastic fibroma (AF), it is now considered as a separate entity in the WHO odontogenic tumor classification. Commonly associated with a painless swelling and an associated
Ameloblastic Fibro-odontoma Clinically: 1- As with ameloblastic fibromas, the ameloblastic fibro-odontoma occurs more frequently in the posterior regions of the jaws. 2- This lesion is commonly asymptomatic and is discovered serendipitously or when radiographs are exposed to provide a diagnosis for asymmetric eruption of the dentition in children. Ameloblastic fibroma and related lesions constitute a group of lesions, which range in biologic behaviour from true neoplasms to hamartomas. This group of lesions is also sometimes referred to as mixed odontogenic tumors and usually includes ameloblastic fibroma, ameloblastic fibrodentinoma and ameloblastic fibro-odontoma.

Ameloblastic fibro-odontoma (AFO) is one of these lesions that previously named ameloblastic odontoma. It composed of dental epi-thelium implanting in an ectomesenchymal tissue like a dental papilla with different amounts and severity. 03 Citation: Hiva Saffar and Leila Aghaghazvini. “Ameloblastic Fibro-Odontoma of Mandible in a 10 Year Boy-A ...

Ameloblastic fibro-odontomas, which are benign mixed odontogenic tumors, account for 0.3% to 1.7% of all odontogenic tumors, but comprise 4.6% of odontogenic tumors in children. 41, 42 Most cases are diagnosed in patients between 9 years to 11 years of age. 41 According to Chang et al., 42 ameloblastic fibro-odontomas usually occur in people ... de Araújo Melo L. et al. Ameloblastic Fibroma: A Rare Case Report with 7-Year Follow-Up odontoma.

The diagnosis was ameloblastic fibro-odontoma, which is a rare mixed odontogenic tumor, derived from epithelial and ectomesenchymal elements that form the dental tissues. 1. Introduction.
