“…Consequently, basis for deciding on an odontogenic derivation for all jawbone cyst with orthokeratinized stratified squamous epithelium is insufficient. In addition, 2 cases of OOC that occurred in the gingiva have been reported previously [29] [30]. In the future, elucidation of the pathogenesis based on the accumulation of further cases and clarification of the molecular pathology will be needed.…”

Background: With transitions in the disease concept of orthokeratinized odontogenic cyst (OOC), the pathogenesis and etiology have not been sufficiently elucidated. Objectives: OOC cases were reclassified and observed to understand the clinico-histopathological characteristics. In addition, literature review of OOC was performed to better organize the pathology. Materials and methods: Subjects with jawbone cysts lined by keratinized stratified squamous epithelium from 2005 to 2018 were reclassified, and clinico-histopathological findings were analyzed. Previous reports of OOC/orthokeratinized-type odontogenic keratocyst (OKC) from 1980 to 2019 were organized. Results: Five cases of OOC were diagnosed, representing 2.1% of odontogenic developmental cysts (total, 239 cases). Mean age was 37.6 years, with a female predominance. The mandibular molar area was the frequent site, and all cysts were solitary. Sixty percent involved an impacted tooth. Mean maximum diameter of the cyst was 2.2 cm. Histopathologically, 4 cases were unilocular, and partial palisading of the basal layer and scattered epithelial islands were observed in 2 cases each and formation of daughter cysts was noted in 3 cases. Previous papers described that most were unilocular and related to impacted teeth. Mean age ranged between 20 and 40 years, and the mandibular molar region was dominant. Recurrence rates were low. Conclusion: OOC shows a different biological attitude to OKC and is closer to dentigerous cyst. Meanwhile, OOC shows a similar histology of epidermoid cysts accompanying the granular layer. We thus surmised that OCC represents an independent concept as an odontogenic developmental cyst.

“…The histopathological characteristics it presents are an epithelium with an orthokeratinized lining, made up of a prominent granulous layer, and basal layer of flattened cuboidal cells that show no trend towards the palisaded nuclear arrangement [1][2][6][7] . Their treatment consists of marsupialization or surgical enucleation 2,7 .…”

RESUMOOs cistos odontogênicos ortoceratinizados são cistos de desenvolvimento de origem odontogênica, de baixa frequência, etiopatogenia desconhecida e baixa taxa de recorrência. Radiograficamente, apresenta-se como uma área radiolúcida em região posterior de mandíbula. O objetivo deste artigo é descrever um caso não usual de cistos odontogênicos ortoceratinizados, que exibia, radiograficamente, focos radiopacos semelhantes à calcificações, no interior da lesão, sugerindo diagnóstico clínico de fibro-odontoma ameloblástico. Após a biópsia incisional e análise microscópica, o diagnóstico conclusivo foi de cistos odontogênicos ortoceratinizados. Observou-se que os focos radiopacos estavam associados, microscopicamente, a presença de uma reação de células gigantes multinucleadas por corpo estranho. O paciente foi tratado cirurgicamente, sob anestesia local, com acesso intrabucal para remoção total da lesão, com o restabelecimento da estética e sem sinais de recidiva após 24 meses. A importância do conhecimento deste tipo de reação dar-se pelo risco de mimetizar uma lesão potencialmente mais agressiva, direcionando a escolha do tratamento da lesão.Termos de indexação: Células gigantes.

Peculiar case of orthokeratinised odontogenic cyst: a peripheral counterpart of the intraosseous entity?

Abstract: We describe a case of an orthokeratinised odontogenic cyst (OOC) in a 49-year-old man, which presented as a submucosal fluctuant, non-tender, soft nodule distal to the inferior right first molar that could be considered a peripheral counterpart of the intraosseous OOC.
