Odontoameloblastoma

Abstract

A case of odontoameloblastoma affecting the left mandible is reported. Initially treated by conservative excision due to its small size, the lesion recurred after 18 months and was treated by radical excision and subsequent reconstruction by a rib graft.

Odontoameloblastoma: A report of a rare case

“…To clarify this confused reporting of cases, the WHO in 2005 subdivided the category into AFO, ameloblastic fibro-dentinoma (AFD) and OA. [ 8 9 ]…”

“…Admixed with these, there might be the presence of structures representing various stages of odontogenesis such as enamel organ, dental papilla and pulpal tissue; sometimes, osteodentin, dentinoid and bone might be present. [ 3 6 8 9 10 13 ]…”

“…Microscopically, there is a subtle distinction between OA, AFO and AFD. [ 8 ] Unlike OA which has a mature connective tissue, both AFO and AFD are composed of loose connective tissue resembling primitive dental papilla intermingled with cords, nests, islands of odontogenic cells and foci of calcified masses. When the calcified masses are similar to dentin and enamel, then term AFO is used.…”

“…For these reasons, OA should be aggressively treated like a conventional ameloblastoma, with wide surgical excision and close follow-up for at least 5 years. [ 8 9 10 11 ]…”

Massive odontoameloblastoma arising in the maxilla: a case report

“…OA is an aggressive odontogenic tumor characterized by simultaneous occurrence of an ameloblastoma and a compound or complex odontoma in the same tumor mass [ 3 , 9 ]. OA affects males and females equally and occurs in the maxilla and mandible, with the molar-premolar area being the most common site.…”
