Ewing's tumours and neuroblastomas

Abstract
From a study of 59 cases of neuroblastoma and 21 patients classified as cases of Ewing's tumour there appear to be differences in age incidence, duration of disease, gross and microscopical appearance, and metastatic spread. The normal rate of excretion of catecholamines by patients with Ewing's tumour is an additional differentiating feature.
