“…Further foci of ameloblastoma islands spread to adjoin area and aggressive curettage of the bone after enucleation is to be avoided.

Because of their increased likelihood of recurrence, patients in Subgroups 1.2.3 and 1.3 need more extensive surgical interventions.…”

There are plenty of benign lesions that can result in swelling of the mandible, and these can be classified as odontogenic and non-odontogenic lesions. Among the categories of odontogenic lesion, ameloblastoma is the most occurring lesion that takes origin from the epithelial cellular elements and dental tissues in their different stages of development. Ameloblastoma is the most serious odontogenic neoplasm due to its prevalence and clinical characteristics. Ameloblastoma is a broad class which encompasses 80% of solid multicystic type of ameloblastoma with unicystic ameloblastoma (UA) variant included as vital clinicopathological form claiming the rest 20% along with peripheral ameloblastoma variant. UA refers to cystic lesions that seem like jaw cysts clinically, radiographically, or grossly but are lined by typical ameloblastomatous epithelium, with or without luminal and/or mural tumor development, on histologic investigation. Around 5–15% of all ameloblastic lesions do not have a propensity to metastasis, and this is UA. Unicystic mural form, although slow growing overall, is very invasive locally and has a high recurrence rate. As UA tumors show very close features with dentigerous cyst, a very sharp differential diagnosis protocol need to be executed to exclude the other unicystic odontogenic lesions considering the clinical, radiological, and biological characteristics along with proper follow-up and seeing any recurrence of the lesion taking place. Here, we report the case of a twenty-one year male patient with UA of the mandible and review of the literature.

“…Few studies have been directed to the analysis of periapical and periradicular ameloblastomas and their similarities with apical periodontitis ( 15 , 21 ). Most papers included isolated AMAP case reports ( 12 , 22 ), and there was only one previously published short series ( 17 ). The present study seems to be the largest series of AMAP including both solid and unicystic ameloblastomas published up to now.…”

Background Ameloblastomas are benign odontogenic tumors that can eventually mimic the clinical and radiological features of apical periodontitis. The aim of the present study was to evaluate the clinical, radiological and histological characteristics from a series of ameloblastomas mimicking apical periodontitis diagnosed in a 14-year period. Material and Methods all cases histologically diagnosed as ameloblastomas from 2005 to 2018 presenting a clinical diagnosis of periapical lesion of endodontic origin were selected for the study. Clinical, radiological and histological characteristics from all cases were tabulated and descriptively and comparatively analyzed. Results Twenty cases composed the final sample, including 18 solid and 2 unicystic ameloblastomas. Mean age of the affected patients was in the fifth decade with predilection for males (72%). The most common anatomical location was the posterior mandible (55%) and most cases presented a radiolucent unilocular (80%) well-defined (95%) image. Most cases were asymptomatic, but the presence of local swelling and bone cortical rupture were common. Conclusions Ameloblastomas mimicking periapical lesions of endodontic origin are mostly diagnosed in adult males as well-defined radiolucent unilocular lesions producing local swelling and bone cortical rupture. Key words: Ameloblastoma, apical periodontitis, cyst, differencial diagnosis, granuloma, periapical lesion.

“…Although UAs are regarded as a less aggressive form of ameloblastoma, the mural form of UA has a high tendency to recur, with one study reporting a recurrence rate of 35% [11,12]. Therefore, the use of less aggressive treatment modalities are recommended to prevent recurrence and a repeat surgery unless UA lesions are widespread or cause aesthetic problems in younger patients [13].…”

Background: Unicystic ameloblastoma (UA) is a rare variant of ameloblastoma and represents about 6% of all ameloblastomas. Radiologically, it is very similar to odontogenic jaw cysts due to its unilocular radiolucency. Case Report: This report discusses the clinical, radiological, histopathological and surgical findings of mural unicystic ameloblastoma occupying the right maxillary sinus on a background of dentigerous cyst associated with an impacted tooth in a 22-year-old female patient. Conclusion: It is very uncommon to see this lesion in the maxilla since it usually involves the posterior region of the mandible. Differentiation of an UA from a dentigerous cyst is radiographically difficult when UA is associated with an impacted tooth. Among all UA types, UA with mural proliferation has the highest rate of recurrence. Long-term follow-up for recurrence should be considered for patients with UA.
