ABSTRACT
Fibroblastic connective tissue nevus (FCTN) is a rare, benign, dermal mesenchymal hamartoma that affects children. We report a 15-year-old boy with a congenital FCTN and describe the clinical, dermatoscopic, and histopathologic features.

INTRODUCTION: The cannabinoid receptor gene 1 (CNR1) encodes the human cannabinoid receptor CB1. This receptor has a widespread distribution in the central nervous system (CNS), the main ligands being anandamide, 2-araquidonoil glycerol and marijuana constituents. There is evidence to suggest an anti-neoplastic effect of these ligands in glial tissues mediated through stimulation of the receptor. MATERIAL AND METHODS: We have studied the G1359A polymorphism of the gene CNR1 with a TaqMan allelic discrimination assay in 200 patients diagnosed with glioma, 109 patients diagnosed with meningioma and 403 healthy subjects. Results Genotypic distribution of the G1359A CNR1 polymorphism in glioma patients showed significant differences when compared to the control group. DISCUSSION: Our results suggest that allele G of the CNR1 gene could be associated with a lower susceptibility to glioma.
