title: Plasma dopamine-beta-hydroxylase in the diagnosis of neuroblastoma.
abstract: An atypical case of neuroblastoma is described, in which the diagnosis was facilitated by the application of a new biochemical procedure, the assay of plasma dopamine-beta-hydroxylase activity. This laboratory tool is proposed as a useful adjunct to established techniques in the diagnosis of neural crest tumors.
