The orthokeratinized odontogenic cyst (OOC) is a rare developmental jaw cyst. Recognition of OOC as a unique entity has long been due, yet its inexplicable radiographic presentation resembling dentigerous cyst, histological likeness to odontogenic keratocyst (OKC) and inconsistent cytokeratin expression profiles overlapping with both as well as with the epidermis, makes it rather confounding. Diagnosis of OOC is important as the pathologic behavior, clinical outcome and the surgical management of OOC is disparate. This is the report of a case of OOC in relation to an impacted mandibular third molar and critical review of this entity with an emphasis on its biologic characteristics is highlighted.

This study investigated the viability of the cell block technique as an auxiliary method of diagnosing jawbone lesions. Thirty-three clinically diagnosed jawbone lesions with a cystic appearance were subjected to aspiration. The aspirated material was processed by the cell block technique, and the lesions were biopsied and treated. Cytological findings (cell block) and histopathology analyses (gold standard) were compared by the chi-square test. There were associations between cysts and cholesterol crystal clefts, between keratocystic odontogenic tumors (KOT) and epithelial cells, and between KOT and parakeratin. The occurrence of cholesterol crystal clefts in cell block slides was correlated with cystic lesions, and the parakeratin presence was a KOT indicator. The cell block technique proved to be fast, easy-to-handle, and low-cost, making it an attractive auxiliary method for the preliminary diagnosis of jawbone lesions.

The solitary or traumatic bone cyst (TBC) is an uncommon non-epithelial lined cavity of the jaws. The lesion is mainly diagnosed in young patients most frequently during the second decade of life. The majority of them are located in the mandibular body between the canine and the third molar. Clinically, the lesion is asymptomatic and is often accidentally discovered on routine radiological examination. The definite diagnosis of traumatic cyst can only be determined at surgery. Often, the material for histological examination may be scanty or non-existent. We present a documented case of a solitary bone cyst involving the body of the mandible. A brief review of literature regarding the main characteristics of the lesion is provided.

Objetivo: Realizar una evaluación epidemiológica de los quistes odontogénicos en pacientes de 0 a 14 años de edad, verificando cuáles son las lesiones de mayor incidencia entre estas edades. Métodos: Fueron evaluadas 100 fichas histopatológicas de lesiones diagnosticadas como quistes de naturaleza odontogénica, enfatizando las características clínicas (género, edad, tipo de lesión quística, localización anatómica y tamaño de la lesión) y radiográficas. Resultados: Fue observado que el género masculino, con edad media de 9, 78 años, así como las regiones posterior de mandíbula y anterior de la maxila fueron más comprometidos. El quiste dentígero fue la lesión más común, seguida del quiste radicular. Se observó además, que en la muestra evaluada el aspecto radiográfico unilocular y las lesiones asintomáticas fueron las más frecuentes. Conclusiones: Se concluyó que es muy importante realizar este tipo de estudios, una vez que a través de ellos podemos conocer la frecuencia e incidencia de diversas lesiones, principalmente en pacientes pediátricos, en los cuales poco se conoce sobre la prevalencia de las lesiones quísticas de los maxilares.
Objective: To realize an epidemiologic survey of odontogenic cysts in patients from 0 to 14 years old in order to find out the most prevalent lesions of each age period. Methods: 100 histopathologic files of lesions diagnosed as cysts of odontogenic origin were retrieved emphasing their clinic (cystic lesion pattern, gender, age, anatomical site and lesion lenght) and radiographic features, which the surgical specimens were forwarded for the Oral Pathology Service of UFRN. Results: It could be identified that either the male gender, with an age average of 9,78 years, or the mandible posterior and the anterior maxilla region were more involved. Dentigerous cyst was the most prevalent lesions, followed by the radicular cyst. Moreover, a unilocular radiolucence and asymptomatic lesions were more common in the sample. Conclusions: To sum up, it can be infered the outstanding relevance of studies like the present since that it is through than that it can be reached the knowledge of the frequency and incidence of several lesions, especially in paediatric patients in as much as the few knowledge of the cystic lesion prevalence in their jaws.

A case of nevoid basal cell carcinoma syndrome is presented and its varied clinical manifestations and multi-system involvement are emphasised. Our case presented with an early onset of symptoms but sought medical help later on for progressively increasing jaw swelling and pain. On further evaluation, multiple pigmented skin papules, palmar pits, multiple jaw cysts, skull bone osteoporosis, bifid ribs and kyphosis were present. Systemic involvement was minimal. There was no significant family history.

Les auteurs presentent les differentes lesions kystiques et tumorales odontogenes sous forme d'une classification fondee sur leur histogenese et sur l'embryogenese des tissus dentaires. Les principaux caracteres radiologiques et anatomo-pathologiques etant definis de maniere nette et aisement memorisable; l'accent est mis sur la therapeutique et le pronostic; sachant que la premiere dicte le second et ne souffre pas d'errement. A cet egard; le probleme principal etant l'ameloblasme; les auteurs decrivent 7 observations d'une lesion gingivale originale; qui en permet aisement le diagnostic
