title: Immunocytochemical demonstration of neuron-specific enolase for differential diagnosis of retroperitoneal tumours in children.
abstract: Six patients with malignant retroperitoneal tumours causing considerable diagnostic difficulties are reported. In a retrospective investigation the presence of neuron-specific enolase (NSE) was analysed immunocytochemically in specimens of these tumours. In all the patients who had finally got the definite diagnosis neuroblastoma, tumour specimens had a strong reaction for NSE whereas all other tumours did not react. An analysis of NSE already at the primary investigation could have led to an earlier definite diagnosis.
