Fine Needle Aspiration Cytology of Retroperitoneal Ganglioneuroblastoma – A Case Report

Abstract

Ganglioneuroblastoma is an uncommon peripheral neuroblastic tumor. They have intermediate malignant potential, in between that of neuroblastomas and ganglioneuromas. Histologically, they are considered to have intermediate malignant potential because they contain primitive neuroblasts along with mature ganglion cells. In literature, reports of this entity being diagnosed by fine needle aspiration and its cytological appearance are scarce.
