Unicystic ameloblastoma (UA) is a less frequently encountered variant of intraosseous ameloblatoma. UA shows clinical and radiological characteristics of an odontogenic cyst but on histological examination a typical ameloblastomatous epithelium lining a part of cyst is evident. A high percentage of these lesions are associated with impacted teeth. Hence dentigerous cyst (DC) is the most common cited provisional diagnosis. An eight year old patient presented with 4-5cm dome shaped swelling in relation to maxillary right region. Radiographically a unilocular radiolucency extending from right canine to molar was noted. On incsional biopsy superficial sections showed histopathological picture of infected odontogenic cyst. However on excisional biopsy, comprehensive sampling, and deeper sections characteristic ameloblastic epithelium was noted, establishing the diagnosis of intraluminal and intramural UA It is essential to differentiate between DC and UA since both the entities call a differing treatment plan. Herein we present a case report of UA and highlighting the role of comprehensive sampling and deeper sectioning in diagnosis of UA.
