Gorlin-Goltz syndrome: Clinicopathologic aspects

ABSTRACT

Gorlin-Goltz syndrome, also known as nevoid basal cell carcicoma syndrome, comes into being due to a genetic alteration produced by a mutation in the “Patched” tumour suppressor gene, and it is inherited in a dominant autosomal way, though sporadic cases have been found. This syndrome shows a high penetrance and variable expressiveness. It is about a multisystemic process that is characterised by the presence of multiple pigmented basocellular carcinomas, keratocysts in the jaws, palmar and/or plantar pits and calcification of the falxcerebri. Together with these major features a great number of processes considered as minor features have also been described. The latter include numerous skeletical, dermatology related and neurological anomalies among others. In some occasions, the presence of very aggressive basocellular carcinomas has been described as well as other malignant neoplasias. Due to the importance of oral maxillofacial manifestations of this syndrome, it is fundamental to know its characteristic in order to make a diagnosis, an early preventive treatment and establish right genetic advice. In this work the main clinicopathologicand the therapeutic aspects related to the syndrome under consideration have been revised and updated
