Unicystic ameloblastoma: A diagnostic dilemma

Unicystic Ameloblastoma (UA) refers to those cystic lesions that show clinical, radiographic or gross features of a jaw cyst but on histologic examination show a typical ameloblastomatous epithelium lining the cyst cavity with or without luminal and/or mural tumour proliferation. (Nagalaxmi et al., 2013) A number of morphological variants of ameloblastoma have been documented in the literature and at times, may pose a diagnostic challenge to the pathologist. (Shaikhi et al., 2012) The dilemma in the diagnosis of UA exists on a radiograph, when it is associated with impacted third molar where it exclusively shows similarity to the dentigerous cyst. Thus, the diagnosis of UA becomes evident only when the entire specimen is evaluated histopathologically. (Laxmidevi et al., 2015) Till date, lot of controversies exist among oral surgeons and oral pathologists regarding this entity. An attempt is being made here to discuss all the diagnostic dilemmas associated with UA. (Arora, 2015) Here, we report one case of luminal, intramural variant of UA in a young male patient.
