RESUMO
Los huesos maxilares constituyen asiento de una gran variedad de quistes y neoplasias que pueden ser de difícil diagnóstico. De entre todos los procesos tumorales que se dan en el territorio maxilofacial, los quistes son de gran importancia debido a la frecuencia de su presentación. Los quistes maxilares tienen distinto origen y comportamiento clínico. A partir de la clasificación de la OMS de 1992, esta revisión estudia las características clínicas, radiográficas y epidemiológicas de los quistes del desarrollo odontógenos. Una adecuada exploración clínica y radiográfica por parte del odontólogo es suficiente para alcanzar un diagnóstico de presunción. Las consideraciones clínicas y terapéuticas de cada uno de estos quistes son variables, por lo que es necesario conocer el comportamiento epidemiológico de ellos. El diagnóstico de presunción, el tamaño de la lesión y la relación de esta con estructuras anatómicas vecinas condicionará el tipo de tratamiento. El diagnóstico definitivo lo dictaminará el análisis anatomopatológico (AU)
The maxillary bones constitute the base of a big variety of cyst and tumours that can be difficult to diagnose. Among all the tumor processes that can occur in the maxillofacial area, cysts are of the utmost importance due to their frequency. Jaw cysts have different origins and clinical behaviour. After the OMS classification in 1992,this review examines the clinical, radiographic and epidemiological characteristics of the cyst of the odontogenic development. An appropriate clinical and radiographic exploration on the part of the dentist is enough to reach a presumptive diagnosis. The clinical and therapeutic considerations of each of these cysts are variable, so it is necessary to know their epidemiological behaviour. The presumptive diagnosis, the size of the cyst and its relationship with neighbouring anatomical structures will determine the type of treatment. The definitive diagnosis will be determined by the anatomical and pathological diagnosis (AU)

Objective: To describe the clinical, radiological and histopathological features of lateral periodontal cysts among patients diagnosed in different centers (Vall dHebron General Hospital, Granollers General Hospital, the Teknon Medical Center, and the Master of Oral Surgery and Implantology of the University of Barcelona Dental School; Barcelona, Spain).Study design: A retrospective observational study was made of 11 lateral periodontal cysts, all of which were diagnosed following a thorough clinical examination, radiological study and posterior histological study.Results: The mean patient age was 37 years, and males predominated over females. The mean lesion size was 1.25 cm. A single relapse was recorded 7 years after removal of the initial lesion. All the cysts were surgically removed.Discussion and conclusions: Lateral periodontal cysts are very infrequent, and are characterized by the preservedvitality of the adjacent teeth. Identification of the lesion is initially based on the clinical findings, though histological study is required to confirm the diagnosis.The treatment of choice is the surgical removal, though occasional relapses have been documented (AU)

Objetives. Botryoid odontogenic cyst (BOC) is considered as an unusual multilocular variant of lateral periodontal cyst (LPC). Review of the literature indicates that this lesion has higher risk of recurrence than LPC, but objetive reasonsare still unknown. The aim of this study is identify main clinical and pathological variables associated with the risk of recurrence. Study design. A complete literature review about cases of BOC was made, from its first description up to the year 2006. A total of 67 cases of BOC were identified from year 1973 (first case) to the last publication in 2005.Results. 85.2% of the BOCs were located in the jaw, affecting to women (54.8% of the cases) in the fifth decade of the life. This lesion shows a well- circumscribed unilocular (60%) or multilocular (40%) radiolucency. Recurrence rate of cases with follw-up data was 32,4%. Conclusions. Size and multilocular patterns could be the main factors associated to recurrence in BOC (AU)

The lateral periodontal cyst and the botryoid odontogenic cyst are two rare nosological entities, who, despite their radiological and clinical presentation can only be diagnosed by their rather typical histopathological characteristics. The purpose of this article is to report two cases of radiolucent cystic lesions of the mandible, located in the premolar area, with a clinical and radiographic diagnosis of residual cyst, which showed histological features of a lateral periodontal cyst. Histopathologically, the lateral periodontal cyst lining is characterized by a thin cuboidal to stratified squamous non-keratinizing epithelium, ranging from one to five cell layers and presence of one or more epithelial thickenings or plaques. Furthermore, glycogen-rich clear cells encountered either in the epithelial plaques or in the superficial layer of the lining epithelium
