Late recurrence in neuroblastoma.

Recurrence in neuroblastoma more than 5 years after diagnosis is extremely rare. One case of neuroblastoma recurring 10 years after complete remission from disseminated neuroblastoma at the 5th month of life is reported. Twelve additional cases in the literature are reviewed. Despite the apparent rarity of this event, it should be considered that the patients with disseminated neuroblastoma induced to complete remission without definitive treatment have a potential for late recurrence and should be followed over long periods of time, especially during puberty.
