Singapore Med J ; Odontogenic neoplasms; Adenomatoid odontogenic tumor; Immunohistochemistry. As previously said, we focused on the ultrastructural detail of the presence, in the luminal surfaces of the adenomatoid structures, of hemidesmosomes and a material similar to the basal lamina, confirmed histochemically by the presence of laminin.

On palpation, the swelling was nontender, hard in consistency, and fixed to the underlying bone. The treatment for AOT is conservative and the prognosis has always been good.

Adenomatoid odontogenic tumor, an uncommon tumor

AOT is a benign, painless, noninvasive, and slow-growing tumor that does not infiltrate the bone.

Aust Dent J ; Sitemap What’s New Feedback Disclaimer. Report of two cases and survey of cases in Japan. It may present as a solid mass, a single large cystic space, or as numerous adenomztoid cystic spaces.


The epithelial cells may form adennomatoid structures around a central space, which may be empty or contain a small amount of eosinophilic material Figure 5.

Two thirds of the cases are found in females. Click here to view. Study on the origin and nature of the adenomatoid odontogenic tumor by immunohistochemistry.

If we consider the cubic cells of the duct-like and adenomatoid structures analogous to post-secretory ameloblasts in their early stage, still capable of secreting some enamel protein, the tendency for absence of CK14 is understandable because this also occurred in normal ameloblasts. Adenomatoid Odontogenic Tumor arising from the manidibular molar region: Not rarely did these structures present a thin layer of the eosinophilic material in its internal surface.

Here, 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.

Br Dent J ; Histological typing of odontogenic tumors, jaw cysts, and allied lesions. This radiolucency covers all crowns, and it overlaps the root of tooth Adjacent to the tumoral proliferation, a cystic lining formed by stratified pavement epithelium was common.

Epithelia in inflammatory areas presented disperse positivity. The immunohistochemical detection of CKs presented intense positivity for CK14 in all epithelial elements Figure 4. Indian J Dent Adv ;1: J Oral Maxillofac Surg. The odontogenic adenomatoid tumor. Odobtogenic are treated conservatively by curettage and enucleation as both are benign in nature. AOTs are relatively small in size. The healing was controlled for three weeks Figure 6.

Histopathological confirmation of the lesion AOT Click here to view. Services on Demand Journal. The intraoral periapical radiograph is the odontkgenic radiograph to show radiopacities in AOT as discrete foci having a flocculent pattern within radiolucency adenomqtoid with minimal calcified deposits.

Int J Pediatr Otorhinolaryngol Extra ;2: On radiographsadenmoatoid adenomatoid odontogenic tumor presents as a radiolucency dark area around an unerupted tooth extending past the cementoenamel junction. None, Conflict of Interest: The specific PCNA cell labelling in the AOTs, not present in the flat and stellate cells among the spindled areas, helped to rule out a neoplastic nature for the tumor. In this paper, a case of AOT in the anterior maxillary region associated with a permanent lateral incisor will be reported.

Tables 2 and 3 summarize the immunohistochemical results obtained using paraffin sections of formalin fixed tissue.
