High incidence of MYCN amplification in a Moroccan series of neuroblastic tumors: comparison to current biological data.

MYCN protooncogene status was assessed for the first time in Morocco in peripheral neuroblastic tumors, including neuroblastoma, ganglioneuroblastoma, and ganglioneuroma. Correlations with age at diagnosis, stage, mitosis-karyorrhexis index, differentiation, and Shimada histology were evaluated. Thirty-six formalin-fixed, paraffin-embedded peripheral neuroblastic tumor tissue specimens collected between 2007 and 2010 from the Pathology Department were assessed for MYCN amplification using fluorescence in situ hybridization.
