Mandibular adenomatoid odontogenic tumor: Radiographic and pathologic correlation

This tumor is uncommon in a patient older than 30 years. The unilocular radiolucency is well demarcated with smooth cortical border.

Report of a case with peculiar features. Introduction Adenomatoid odontogenic tumor AOT is an uncommon benign odontogenic lesion that affects young patients associated with an impacted tooth, usually canine. A possible differential diagnosis for the lesion described in this case report is a dentigerous cyst and an adenomatoid odontogenic tumor.

The history revealed an orthodontic treatment started in December with arenomatoid treatment plan involving extraction of teeth 34, 44, 23, and The buccal cortex is expanded and the surface of the swelling is smooth.

Study on the origin and nature of the adenomatoid odontogenic tumor by immunohistochemistry

Pericoronal radiolucencies with opacities. Histological typing of odontogenic tumors, jaw cysts, and allied lesions.


The buccal cortex was expanded, and the surface of the swelling was smooth with a normal color of overlying mucosa. Immunohistochemical localization of amelogenin in human odontogenic tumors, using a polyclonal antibody against bovine amelogenin.

Cytokeratins in epithelia of odontogenic neoplasms. Usually, they do not exceed cm in diameter. The characteristic duct-like structures are lined by a odontogeenic row of columnar epithelial cells, the nuclei of which are polarized away from the central lumen, as was evident in all our cases.

The adenomatoid odontogenic tumors presented epithelial proliferation in which cells placed in solid nodules forming sheets, or a nest-and cord-like pattern. The results have shown that CK14 labelling indicated differentiation grades for secreting ameloblasts or ameloblasts in the post-secreting stage in the adenomatoid structure of AOT.

Variants of the adenomatoid odontogenic tumor with a note on tumor origin.

Odontogenix, we report a case of AOT arising from the dentigerous cyst with an impacted canine in the anterior maxilla in a year-old boy with emphasis placed on clinical, radiographic, and histological features in addition to its surgical management.

A radiolucency cyst-like was noted on the lateral incisor Figure 1 and was diagnosed as a dentigerous cyst. Extra oral examination There is diffused swelling involving adenomatod anterior maxilla with moderate obliteration arenomatoid nasolabial fold [ Figure 1 ]. Report of thirteen cases. Int J Pediatr Otorhinolaryngol Extra ;2: Clinically, these lesions cannot be differentiated from the common gingival fibrous lesion [ 34 ]. Head Neck Pathol ;5: On radiographsthe adenomatoid odontogenic tumor presents as a radiolucency dark area around an unerupted tooth extending past the cementoenamel junction.


Adenomatoid odontogenic tumor

A case report and review of literature. The underlying connective tissue was fibrous, thick, with extensive areas of hemorrhage and discrete inflammatory mononuclear infiltrate. Two thirds of the cases are associated with an impacted tooth usually being the canine.

J Oral Pathol Med. Diagnostic imaging of jaws; p. AOTs are benign and present a very low recurrence, making it unnecessary to carry out extensive and aggressive surgery [ 23 ]. A surgical exposition of the crown and bonding of a bracket on the maxillary left lateral incisor were also planned a coronoplasty of the first premolar to a canine shape.

Although it affects odontogeni individuals, mainly females, commonly found in the anterior maxilla and associated with an impacted canine, this was not so in our analysis.

Primary antibodies were then incubated; their sources, concentrations, and times of incubation are listed in Table 1.

The skin over the swelling appeared normal.
