title: Late manifestations of esthesioneuroblastomas in the central nervous system: report of two cases.
abstract: Two patients with esthesioneuroblastomas that disseminated in the central nervous system (CNS) and elsewhere are reported. The latest recurrences in the CNS were 19 years after the diagnosis in patient and 9 years after the diagnosis in the other. Because the treatment of patients with such late recurrences is complicated by previous surgical procedures and radiation therapy, we review therapeutic options for these patients. The literature has not previously stressed the occurrence of late metastases, including those to the CNS, after prolonged disease-free intervals.
