The adenomatoid odontogenic tumor (AOT) is an uncommon benign, non-invasive tumor also known as “two-thirds tumor,” which is either intra or extraosseous. The extraosseous AOT is also referred to as peripheral, gingival or soft tissue odontogenic tumor. Gingiva is a common site for reactive lesions, benign neoplasms and distant metastasis. Peripheral adenomatoid odontogenic tumor (PAOT) is a rare entity with an incidence of only 3% of all reported AOTs. It is primarily described as a slow-growing gingival swelling with minimum or no bone involvement. It presents highest predilection for maxillary gingiva of anterior teeth and predominantly affects children. Till date 22 PAOT's have been reported worldwide and their behavior is similar to intraosseous AOTs. Thus, the clinician should be aware while treating them. The present case describes an additional case of PAOT on the maxillary anterior gingival region of a 15-year-old female. Key messages: AOTs called as “master of disguise” and peripheral ones commonly resemble gingival lesions. Gingiva is a common site for reactive and neoplastic conditions. So, care must be taken for its proper diagnosis, timely treatment and follow-up.
