title: Neurofibromatosis and associated neuroectodermal tumors: a congenital neurocristopathy.
abstract: The synchronous occurrence of neurofibromatosis and neuroblastoma has been labeled in the recent literature as a chance event. We report 2 cases of newborn infants with congenital neurofibromatosis and a similar midline pattern of multiple Schwann cell and neuroblastic tumors; other types of ectomesenchymal tumor differentiation are documented, along with supportive ultrastructural and immunohistochemical studies. The tumors may take an aggressive, fatal course despite maximal multimodality antitumor therapy. These 2 cases are reported, with additional literature review, to document a clinically recognizable neurocristopathy that links neuroblastic tumors and neurofibromatosis.
