“…Although both lesions affecting this community display expansion, the pattern of expansion associated with KCOT is more likely to be fusiform than the balloon-like expansion of the ameloblastoma; compare Figure 2 with MacDonald-Jankowski and co-authors' 7 Figure 4. This pattern of growth arises from the propensity of the KCOT to extend mesiodistally through the body of the mandible, with minimal expansion.…”

“…This is important as Hong Kong Chinese are already known to display features in three benign odontogenic neoplasms [4][5][6][7] that differ from other communities. Therefore, a review of this newly recognized odontogenic neoplasm affecting this community is merited.…”

Objectives: The aim of this study was to evaluate the clinical and conventional radiological features of a consecutive series of cases of ''keratocystic odontogenic tumour'' (KCOT) affecting a Hong Kong Chinese community and to determine their outcome by follow-up. Methods: All cases were accompanied by appropriate radiography and were histopathologically confirmed. Results: 33 consecutive KCOTs were reviewed. 18 patients were male. The mean age at first presentation was 30.6 years. Swelling was the most frequent presenting symptom. Those patients first presenting with pain were significantly older, whereas those first presenting with a maxillary lesion were significantly younger. The maxilla and mandible were affected in 13 and 20 cases, respectively. KCOTs were most frequently confined to the posterior sextants of both jaws. KCOTs affecting the maxilla were mainly unilocular, whereas those affecting the mandible were multilocular. Patients with multilocular KCOTs were significantly older. Patients with KCOTs associated with root resorption were significantly older, whereas patients associated with unerupted teeth were significantly younger. 69% displaced teeth, 41% resorbed them and 56% were associated with unerupted teeth. All but two were followed up for at least 2 years. Three lesions recurred. Conclusions: KCOTs in this community displayed some differences from those reported in the literature.

Objectives: The aims of the review were to evaluate the principal clinical and conventional radiographic features of orthokeratinized odontogenic cyst (OOC) by systematic review (SR), and to compare the frequency of OOC between four global groups. Methods: The databases searched were the PubMed interface of MEDLINE and LILACS. Only those reports of OOCs that occurred in a consecutive series of OOCs in the reporting authors' caseload were considered. Results: 37 reports on 36 case series were included in the SR. OOC affected males twice as frequently and the mandible almost 2.5 times as frequently. Although the mean age at first presentation was 35 years, the largest proportion of cases first presented in the third decade for the Western, East Asian and Latin American global groups. Seven reports included details of at least one clinical finding. 11 reported case series included at least 1 radiological feature. All OOCs were radiolucent, 93% were unilocular and 68% were associated with unerupted teeth. 28% of the reported case series included follow up. 4% of OCC recurred and all of these were in the Western global group. Conclusions: Although one feature of OOCs is that they are unlikely to recur, some do. Not only is there a lack of long-term follow up of large series with long-term outcomes of OOC, but there is a paucity of clinical and radiological details of OOC at initial presentation.

Sin embargo, este tipo de imagen ofrecía información limitada sobre la afección a tejidos blandos y las características internas de la lesión.…”

RESUMENDe acuerdo con la Organización Mundial de la Salud (OMS), el ameloblastoma es un tumor odontogénico benigno, siendo una de sus variantes intraóseas más frecuentes el ameloblastoma sólido o multiquístico, el cual tiene un comportamiento local agresivo por su capacidad de alcanzar grandes dimensiones y desplazar estructuras anatómicas vecinas. Se reporta el caso de un paciente masculino que presentaba un ameloblastoma sólido en la mandíbula, de 7 años de evolución, que producía marcada asimetría facial y limitación de la función de la zona anatómica afectada. Debido a las dimensiones de la lesión, se utilizaron diversas técnicas imaginológicas con la fi nalidad de contribuir en el diagnóstico, determinar la extensión de la lesión y planifi car el tratamiento. Se presenta una revisión de la literatura sobre tomografía computarizada (TC) e imagen por resonancia magnética (IRM) del ameloblastoma, cuyo objetivo es contribuir a defi nir sus características imaginológicas. Se enfatiza la importancia de estas técnicas de imagen modernas en el proceso de diagnóstico, planifi cación del tratamiento quirúrgico y el seguimiento a largo plazo de esta patología.PALABRAS CLAVE: Ameloblastoma, tomografía computarizada espiral, imagen por resonancia magnética.

Ameloblastoma in the Hong Kong Chinese. Part 2: systematic review and radiological presentation

Abstract: Radiologically, ameloblastomas in the Hong Kong Chinese differ significantly with regards to many features. This can be in part explained by the higher proportion of the unicystic form.
