[Gorlin cyst and clinicopathological aspects]

ABSTRACT

Gorlin cyst is an odontogenic lesion with different clinical behavior. There are different ideas about its nature as a cyst or tumor. The purpose of this study is evaluation of the frequency as well as clinical, pathological and radiographic aspects and also the related treatment. In a retrospective study, archive files of Dental Faculty of Babul from 2003-2009 were evaluated. The records of those patients with Gorlin cyst were excluded. After extraction of all the required information, they were recorded in SPSS, version 17. Frequencies of the mentioned cyst and also patients' recorded information were analyzed by Fisher exact test. From 443 patients with oral lesions; 20 cases were reported with Gorlin cyst [an average age of 28.4], 19 cases with central lesion and 16 cases with mandible lesion and 10 cases were found in male. According to the Radiographic reports; 14 cases were pericoronal radiolucency, 2 cases were periapical radiolucency and 2 cases were radiolucent radiopaque. Only one case was revealed with residual cyst. Various kinds of proliferative [1 case], non proliferative [11 cases], correlate with tumor [5 cases] and ameloblastomatous [3 cases] were observed pathologically. Treatment approaches differed from Enucleation [n=13] to Enucleation and currettage [n=5] to Marginal resection [n=2]. Gorlin cyst is less common among all the oral lesions. It was found that Gorlin cyst was more common in mandible in second half of the life and its frequency between male and female was the same. Central lesions were more common than peripheral. The most common radiographic, pathological and treatment aspects of Gorlin cyst sequentially consisted of pericoronal radiolucency, non proliferative and enucleation
