Keratocystic odontogenic tumour arising as a periapical lesion

Abstract: Benign and malignant tumours, including odontogenic lesions, can be erroneously diagnosed as periapical radiolucencies. KOTs mimicking periapical lesions of endodontic origin are uncommon, especially when the lesions involve the maxilla. This article describes a 55-year-old man with a well-delimited, oval-shaped, radiolucent lesion, occupying the middle and apical third of teeth 22 and 23. After 30 days, the clinical and radiographic findings remained unchanged and the patient was referred for surgical removal… Show more

“…Jeyaraj et al 9 descrevem um percentual elevado de reincidência para essas lesões (sindrômicas -82%), quando comparado a episódios de ceratocistos solitários (não sindrômicos -61%). Além disso, comparações entre ceratocistos sindrômicos e não sindrômicos revelam que, na SGG, estes tumores são múltiplos, exibem maior incidência de paraqueratinização do epitélio e apresentam número aumentado de células satélites e ilhas sólidas de proliferação epitelial 7,[11][12][13][14][15][16][17][18][19] .…”

“…A consequence of infection of the root canal system involves progressive stages of inflammation and changes of periapical bone structure, characterized by apical periodontitis (2). Apart from endodontic origin (3,4), periapical lesions may be of non-endodontic origin (5).…”
