Introduction: Practitioners often misdiagnose Adenomatoid Odontogenic Tumor (AOT) due to its clinical appearance that resembles dentigerous cysts and ameloblastoma. It represents hamartomatous malformation and has ductus-like structure and rose-like appearance with varying degrees of changes in its surrounding connective tissue. This tumor is of benign and non-invasive type and has low recurrence rate. It is very crucial to conduct histopathological examination as an important adjunct in discussing clinical, radiographic and histological findings in addition to enucleation biopsy as the surgical management.
Purpose: The aim of this study is to report the management of adenomatoid odontogenic tumor found in the anterior region of mandibula. The findings of this study will keep the practitioners updated in establishing the diagnosis of AOT compared to other jaw lesions.
Case Report: A 15-year-old male patient consulted with chief complaints of a 3 x 2 x 1 cm asymptomatic swelling in the left anterior portion of the mandible since 6 months before being referred to our department. The swelling initially appeared in patients gum and had developed to be in larger and longer size. The surface of the lesion was smooth with firm & immobile consistency and associated with mandibular lateral incisors & canines impaction.
Discussion: Adenomatoid Odontogenic Tumor is an uncommon benign epithelial lesion and represents only 2-7% of all odontogenic tumors associated with unerupted permanent canines. It has a striking tendency to occur in the maxilla especially in young females. In this case, we reported an uncommon finding of adenomatoid odontogenic tumor in the anterior portion of the mandible from a young man.
Conclusion: The management of AOT in this case was conducted with enucleation biopsy and pharmacological approach. The result of post-operative evaluation was very good.
Key words: Enucleation Biopsy, Adenomatoid Odontogenic Tumor
