ganglioneuroma, retroperitoneal, laparotomy, immunohistochemistry
Retroperitoneal ganglioneuromas arise from the sympathetic ganglion cells and are usually considered as benign tumours. They develop as slowgrowing abdominal masses and require a differential diagnosis supported by pathologic assessment. Because of their benign nature, adjuvant chemoradiotherapy is not indicated in the treatment of ganglioneuromas for which carefully planned follow-up examinations are commonly suggested. Here, we report a case of a retroperitoneal ganglioneuroma treated with complete surgical removal.
