Oral and maxillofacial pathology. The buccal cortex was expanded, and the surface of the swelling was smooth with a normal color of overlying mucosa. Craniopharyngiomas, derived from the remnants of Rathke’s pouch or a misplaced enamel organ, are also comparable to the odontogenic tumors.

Pathology Outlines – Benign tumors / tumor-like conditions: adenomatoid odontogenic tumor

Adenomatoid odontogenic tumour adenoameloblastoma. Immunohistochemical analysis of apoptosis-related factors Fas, Fas ligand, caspase-3 and single-stranded DNA in ameloblastomas.

The extraction of the impacted left maxillary canine was recommended due to its buccal position and absence of the vestibular cortical bone as shown on tumorw Cone Beam Computerized Tomography CBCT Figure 1. Notes No potential conflict of interest relevant to this article was reported. D, H Abortive tooth materials asterisk produced by epithelial tumor cells.

Case Rep Dent ; Based on the striking histological similarity of craniopharyngiomas and odontogenic tumors, craniopharyngiomas can be divided into adamantinomatous and papillary variants according to the WHO classification of odontogenic tumors. The odontoegnic duct-like structures are lined by a single row of columnar epithelial cells, the nuclei of which are polarized away from the central lumen, adenonatoid was evident in all our cases.

Intraoral examination Figure 2 b revealed a solitary smooth circumscribed swelling of 1. Head Neck Pathol ; 1: Therefore, it is suggested that comprehensive pathological observation including molecular genetic information can provide a more reliable differential diagnosis for the propagation and prognosis of ameloblastomas and AOTs. In this paper, a case of AOT in the anterior maxillary region associated with a permanent lateral odontogeic will be reported.


Case Reports odontogeniv Dentistry. The relationship of adamantinomatous craniopharyngioma to ghost cell ameloblastoma of the jaws: The skin over the swelling appeared normal.

Korean Journal of Pathology ; 47 3: A year-old female child reported to our clinic with a complaint of missing teeth in the right maxilla with a medical history taking epileptic drugs. This material may stain for amyloid [ 310 ].

InAOT was described as pseudo-adenoameloblastoma by Dreibladt.

Case Reports in Dentistry

Qian Y, Huang HZ. Adenomatoid odontogenic tumor, an uncommon tumor.

Abstract Here we report a case of adenomatoid odontogenic tumor AOT in the maxilla in a young girl aged 14 years odnotogenic its surgical management. Oral Maxillofac Surg ; The clinical course of ameloblastic carcinomas is typically aggressive, with extensive local destruction.

Unicystic ameloblastoma of the mandible. Pathological analysis of the basal cell carcinoma.

A possible differential diagnosis for the lesion described in this case report is a dentigerous cyst and an adenomatoid odontogenic tumor. Tuftelin mRNA is expressed in adenomatoir human ameloblastoma tumor.

Epithelial growth factor receptor expression had no statistical significance for local recurrence, patient age, or tumor size, whereas a significant relation existed between CD10 expression and the Ki labeling index, which is significantly related to the recurrence of ameloblastomas.

Adenomatoid odontogenic tumor

BMJ Case Rep ; Radiographic findings Well-circumscribed radiolucent lesion same in right maxilla with impacted teeth 13 and 14, with well-defined radio-opaque border. The unilocular radiolucency is well demarcated with smooth cortical border.


Larger lesions cause a painless expansion of the bone [ 38 ].

AOT is a rare slow-growing painless, noninvasive tumor, often misdiagnosed as an odontogenic cyst. Plexiform odontoegnic The plexiform type contains epithelium that proliferates in a “fish net pattern,” or in a “cord-like fashion anastomosing each other,” hence the name “plexiform.

Mandibular adenomatoid odontogenic tumor: Radiographic and pathologic correlation

Biological profile based on cases. New author database being installed, click here for details. However, different epithelial odontogenic tumors can be classified into ameloblastomas, adenomatoid odontogenic tumors AOTscalcifying epithelial odontogenic tumors, odontogenic ghost cell tumors, squamous odontogenic tumors, ameloblastic fibromas, ameloblastic fibroodontomas, or odontomas, etc.

Compared to ameloblastomas, AOT is a benign, nonaggressive tumor with limited growth and no tendency of recurrence. Pain or other neurologic signs are not characteristic. In this case, AOT was associated with the lateral maxillary incisor.

On extraoral examination Figure 2 afacial asymmetry was noted. The current WHO classification of odontogenic tumors defines AOT as being composed of odontogenic epithelium in a variety of histoarchitectural patterns, embedded in mature connective tissue stroma, and characterized by slow but progressive growth.

In stafne reported first series of AOT under the title epithelial tumors associated with developments cyst of maxilla.

There are three variants of AOT: AOT has three variants, follicular, extrafollicular, and peripheral.
