“…Secondly, radiographic examination usually reveals a well circumscribed radiolucency associated with an impacted tooth, but in the present case the radiolucency was large, ill-defined and associated with root resorption of 14, 15, 16, which is quite uncommon. In fact, to our knowledge, only 4 cases of AOT with root resorption have been reported (9,10,20,21). Thirdly, a fibrous capsule is present around the tumor, but this feature was absent in the present case, suggesting its aggressive nature.…”

Adenomatoid odontogenic tumor (AOT)is an uncommon tumor of odontogenic origin with a relative frequency of 2.2 -7.1%. As the histogenesis of AOT is still uncertain, it is sometimes categorized as a hamartomatous lesion rather than a true neoplasm. We report a case of AOT in the right maxillary anterior region in a 20-year-old woman. The tumor showed some unusual and aggressive features that suggested it was a true neoplasm.

“…An unerupted maxillary canine is the tooth most commonly associated with AOT (4). Irregular root resorption is seldom reported (10). Clinically, AOT presents as a slow-growing symptom-free lesion and is frequently discovered during routine radiographic examination (11).…”

Adenomatoid odontogenic tumor - a rare cause of jaw swelling

Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin, characterized histologically by the formation of ductlike structures with amyloid-like deposits. Histogenesis of AOT is still uncertain and it is often considered as a hamartomatous lesion rather than a true neoplasm. AOT has a benign behavior and conservative surgical enucleation or curettage is sufficient. We report a case of AOT in a 15-year-old female who presented with left-sided jaw swelling with tooth resorption. Histopathology revealed intraosseus follicular variant of AOT. A brief review of literature is also discussed.

“…A further very unusual case, which could represent an AOT developing in an ameloblastoma, was reported by Nomura et al [18]. This lesion occurred in a 64 year old Japanese man who exhibited a large destructive lesion in the mandible, which had proliferated intra-orally into the overlying gingivae.…”

The follicular variant of the adenomatoid odontogenic tumor (AOT) is thought to originate from the reduced enamel epithelium of the dental follicle. The origin of the extra-follicular variant however, remains less clear. This paper presents a case of an extra-follicular AOT, which we believe originated from the epithelial lining of a unicystic ameloblastoma, and reviews the literature. The available evidence seems to indicate that some extra-follicular AOTs might arise as secondary phenomena within pre-existing odontogenic cysts or cystic tumors.
