The calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic tumor constitutes around 1% of all odontogenic tumours involving the jaw. The intraosseous and extraosseous variant constitutes about 95% and 5% of CEOT respectively. We have reported two CEOT cases. One is associated with an impacted left third molar in the maxilla of 39-year-old female patient, and the other with a sessile soft tissue gingival mass in the left molar region of a 30-year-old female patient. It also emphasizes the importance of advanced imaging and peculiar findings of computed tomography in diagnosing this rare tumour. The visualization of the internal structure of the lesion and the involvement of the neighbouring structures were considered very helpful for diagnosis and treatment planning. Early detection and treatment planning for such rare cases is required to prevent further complications.
Odontogenic keratocyst (OKC) has always been a subject of interest for researchers and clinicians, owing to its unique pathogenesis, aggressive clinical behavior and association with syndromes. Majority of OKCs occur in the mandibular posterior region, and sporadic type of cysts have a predilection to occur in males and in patients of older age groups. The present article reports a case of sporadic OKC presenting in a relatively unusual manner, occurring in the maxillary anterior region of a young female patient. Unlike other reported cases that found OKC prior to commencement of orthodontic treatment, herein it had possibly occurred as a complication of the orthodontic treatment. The article also depicts characteristic microscopic features of OKC such as uniform parakeratinized lining with multiple infoldings, basal palisading, areas of interface separation between the lining and capsule. Disrupted lining with severe inflammatory cell infiltrate in the capsule was indicative of secondary infection
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
