Cisto queratocisto: revisão de literatura

Abstract

INTRODUCTION: The Keratocyst Cyst, is a type of cyst that presents keratinization of its epithelial lining, being covered by a uniform stratified squamous epithelium, and a basal layer composed of columnar or cuboidal cells arranged in a palisade, with or without the presence of cells inflammatory. Because of its histological characteristics, kinetic proliferation and behavior, the Keratocyst is considered a distinct entity. For this reason, the specific histological pattern of the Keratocyst differs from the others. During their growth, they promote bone resorption, which can cause the bone that covers them to become very thin, producing the sensation of "eggshell" when com- pressing it. OBJECTIVE: To carry out a bibliographic survey of the literature on this pathology, to present its diverse characteristics, considerations in the clinical-radio- graphic - histological aspect and the lesions that are part of the Differential Diagno- sis, as well as the forms of treatment. METHODS: This study is exploratory and des- criptive, carried out through a literature review. The search was performed in the PubMed database. The search words used were: Odontogenic Keratocyst, Odonto- genic Cyst, Odontogenic Tumor and Keratocyst Cyst. RESULTS: The keratocyst cyst mainly affects the mandible (75% of cases), and it is more common to reach the third molar area. It does not present any specific symptoms, and its main characteristic is the high rate of recurrence after surgical removal (25 to 60%). Decompression and marsupialization are beneficial methods that result in a considerable reduction in the cystic volume and less chance of injury. FINAL CONSIDERATIONS: Despite presen- ting complexity in its description, it is a type of tumor classified as benign in histo- pathological exams and does not cause metastases.
