Maxillary cysts, including the cysts lined by respiratory epithelium, can present a diagnostic challenge. We report an unusual case of a maxillary cyst on an endodontically treated tooth #16, in which the cavity was totally lined by a respiratory epithelium. The patient, a 35-year-old male, presented with a generalized chronic periodontitis and complained of a pain in the tooth #16 region. A pe...

Dentigerous cysts are the second most common developmental odontogenic cysts after radicular cyst. They usually present in the second or third decades of life and these cysts are rarely seen during child hood. Their frequency in the general population has been estimated at 1.44 cysts for every 100 unerupted teeth. According to frequency of impaction, the maxillary permanent canine ranks second ...

BACKGROUND Cysts of the jaws constitute an important pathology in the oral and maxillofacial region and are broadly classified as odontogenic and non-odontogenic. Objective of this study was to document the clinical and radiographic presentation of odontogenic cysts at a tertiary care centre. METHODS In this descriptive case-series, patients presenting with features of suspected cystic lesion...

OBJECTIVES Orofacial cysts are broadly divided into odontogenic and nonodontogenic types, epithelial or non-epithelial, and developmental or inflammatory in origin. The odontogenic cyst is an osseous-destructive lesion that most commonly affects the jaw. It is formed by activation of odontogenic cell rests entrapped within the bone or gingival tissue of the jaws, such as the epithelial remains ...

Intraspinal synovial cysts are infrequent causes of back and radicular leg pain. Commonly associated with degenerative spinal disease, the majority of synovial cysts appear in the lumbar spine. Rarely, intracystic hemorrhage can occur through an unclear mechanism. Similarly rare, cysts may also become migratory. The pathogenesis of hemorrhagic synovial cysts remains uncertain and their potentia...

OBJECTIVE Synovial cysts of the vertebral facet joints are a source of nerve root compression. Different surgical procedures are in use, but no consensus has been formed so far as to which method should be used in synovial cysts. To clarify the role of surgical management, the efficacy of operative procedures and factors influencing the outcome in our own series of 19 patients treated between 1...

INTRODUCTION Odontogenic cysts constitute a group of frequent intraosseous lesions characteristic in the maxillary bones and one of the main causes of the destruction of these bones. In Chile there are no retrospective studies of these lesions as a whole. OBJECTIVE The purpose of this study is to determine the frequency of these lesions in so far as they were diagnosed and registered in the R...

Background: Cystic echinococcosis (CE) is a zoonosis caused by the larve of Echinococcus granulosus. Cysts can develop in any part body, although liver and lungs are most frequently involved. Bone one rarest forms disease, accounting for 0.5 to 4.0% all echinococcosis. Spinal cysts disabling causing destruction similar malignant bone lesions, with high risk neurological deficit. Objectives: To ...

BACKGROUND the objective of this study was to describe the frequency of cystic lesions in a Brazilian population of patients histopathologically diagnosed in the first and second decade of life. MATERIAL AND METHODS Retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from the archives of a Brazilian referral center between 1980 and 2016. RESULTS A tot...
