Extrafollicular adenomatoid odontogenic tumor mimicking residual cyst

Two sides of a coin: A report of two contrasting cases of adenomatoid odontogenic tumor with unusual presentations

“…Philipsen and Birn described the following variants of AOT as per its clinical and radiographic presentation:[ 2 4 6 ]…”

“…AOT, the fourth most frequently occurring odontogenic tumor accounting for up to 3–7% of all odontogenic tumors,[ 3 6 7 ] is a benign, usually nonaggressive and noninvasive odontogenic epithelial tumor and is referred to as “two-third tumor” as in two-thirds of the cases, it occurs in young females, two-thirds of the cases arise in the maxilla, and two-thirds of the cases are associated with an unerupted canine. Since it occurs in the alveolar process of the jaws usually associated with an unerupted tooth having components of the dental lamina, enamel organ, reduced enamel epithelium, and/or their remnants, AOT is believed to originate from the odontogenic epithelium[ 7 ] although its origin is controversial.…”
