Abstract

<abstract abstract-type="main" id="jop12035-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="jop12035-sec-0001" sec-type="section"> <title>Background</title> <p>The glucose transporter type 1 (GLUT‐1) protein is a useful marker for perineurial cells. Because of the possible neuroectodermal histogenesis of the granular cell tumour and congenital granular cell epulis, the aim of this study was to assess the immunoexpression of GLUT‐1 protein in granular cell tumour and congenital granular cell epulis to aid in clarifying their histogenesis.</p> </sec> <sec id="jop12035-sec-0002" sec-type="section"> <title>Methods</title> <p>The protocol of this study was approved by the Committee of Bioethics in Research at Universidade Federal Minas Gerais. Six cases of granular cell tumour and three cases of congenital granular cell epulis were submitted to immunohistochemistry for GLUT‐1 and S‐100 using the streptavidin‐biotin standard protocol.</p> </sec> <sec id="jop12035-sec-0003" sec-type="section"> <title>Results</title> <p>Five cases of granular cell tumour were located on the tongue and one case on the upper lip. All cases of congenital granular cell epulis were observed in the alveolar ridge of newborns. All lesions evaluated proved to be immunonegative for GLUT‐1. S‐100 was found to be positive in all granular cell tumours and negative in congenital granular cell epulis.</p> </sec> <sec id="jop12035-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Neither granular cell tumour nor congenital granular cell epulis is directly related to perineurial cells.</p> </sec> </abstract>
