title: Pineal neoplasms and third-ventricular teratomas in Niigata (Japan) and Western Australia. A comparative study of their incidence and clinicopathological features.
abstract: It is claimed that Japan has the highest incidence of pineal neoplasms in the world. To test this hypothesis, we reviewed all pineal neoplasms and third-ventricular teratomas that were diagnosed histopathologically and treated neurosurgically over 10 years (1975-1984) in Niigata City, Japan (12 patients) and in Perth, Western Australia (9 patients). The age-standardized incidence rates per million person-years were 0.61 for Niigata and 0.70 for Western Australia; thus, the contention that Japan has the highest incidence in the world of pineal neoplasms is not confirmed.
