“…Irregular root resorption is seldom reported (1,6). The patient we describe in this report also presented resorption of the upper left lateral incisor and first premolar, together with impaction of the canine.…”

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.

“…The canine maxillary area is the predilection site of AOT. 8,21 In our case, the tumor was located in the left mandibular anterior region, which is a rare though previously described location. 22 AOT are generally and typically asymptomatic lesions, but may cause cortical expansion.…”

Purpose: To investigate for the first time the immunohistochemical and mutational status of b-catenin in a mandibular case of adenomatoid odontogenic tumor (AOT) and to review the immunohistochemical expression data of various markers (cytokeratins, metalloproteinases, etc) in such a lesion. Materials and Methods:A case of follicular-type AOT in a young male patient was analyzed in regard to the immunohistochemical expression of b-catenin and mutations of the b-catenin gene (CTNNB1). Its expression is altered in some odontogenic tumors.Results: We found a strong cytoplasmic expression of b-catenin, but no molecular anomaly within the exon 3 of CTNNB1. b-catenin is considered to play a role in cell differentiation processes. Conclusion:Our results were consistent with previous findings in ameloblastoma and malignant odontogenic tumors. However, b-catenin alterations had not been explored in AOT so far. Further studies are necessary to understand the specific regulation of b-catenin in the AOT pathogenesis. Ó

“…These tumors present a very low recurrence and conservative surgical enucleation with the extraction of the associated tooth is the treatment modality of choice. 1 We present a follicular variety of this infrequent benign tumor, affecting the anterior region of the mandible, associated with an impacted lower left canine and another case of extrafollicular variety in the posterior mandible in a 32-year-old patient.…”

“…1,2 Many different names, like adenoameloblastoma, ameloblastic adenomatoid tumor, adamantinoma, epithelioma adamantinum or teratomatous odontoma have been used before to define this lesion. 3 It is predominantly found in young and female patients, is usually located in the anterior region of the maxilla associated with unerupted teeth, frequently canines or lateral incisors.…”

Adenomatoid odontogenic tumor (AOT) is a benign odontogenic lesion that affects young patients, with female predominance, mainly in second decade. It exhibits distinct histopathological features. We present a clinicopathological analysis of two cases of AOT affecting the mandible in 18 and 32 years old male patient respectively. The first case was of follicular AOT involving mandibular left canine and the second case was observed in the mandibular right posterior region representing extrafollicular variant of AOT. AOT frequently resembles more common lesions of odontogenic origin, such as dentigerous cysts or ameloblastomas, and it should be distinguished from these lesions in routine dental examinations.
