title: A rare case of extrafollicular adenomatoid odontogenic tumour in the posterior region of the mandible: misdiagnosed as residual cyst.
abstract: Adenomatoid odontogenic tumor is a relatively uncommon distinct odontogenic neoplasm. It is an uncommon tumor of odontogenic origin with varying number of ductlike structures and inductive changes in the stroma. It is a benign and slow growing epithelial tumor and represents 3% of all odontogenic tumors. Its occurrence is more common in anterior region of the maxilla than mandible. Most of the adenomatoid odontogenic tumors occur intra-osseously but few peripheral variant have been reported which are attached to the gingival structures. The intra-osseous Adenomatoid odontogenic tumor may be related to unerrupted tooth (follicular varient) or may not (extrafollicular varient) be related to unerrupted tooth. This paper is to present a rare case of an extrafollicular Adenomatoid odontogenic tumor occurring in the body of the mandible in a male patient which is distinct and secondly it was clinically and radiographically diagnosed as residual cyst. The diagnosis of Adenomatoid odontogenic tumor was confirmed by Histopathological investigation. How to cite this article: Shivali V, Khanna VD, Khanna P, Singh A, Pandey A, Ahuja T.
