title: Molecular genetics of pineal region neoplasms.
abstract: A large variety of mass lesions have been reported in the region of the pineal gland. Pineal parenchymal tumors and germ cell tumors (GCTs) are especially characteristic of this region. Despite their rarity, a number of excellent studies on the cytogenetics and molecular genetics of pineal parenchymal tumors and pineal region GCTs have been published. These studies draw attention to a number of distinct genomic regions recurrently involved in the various subtypes of malignancies of the pineal gland. Outcomes for tumors in this location vary widely between patients and among differing histologies. Development of novel therapies for patients with poor prognoses will depend on the acquisition of a more detailed understanding of the molecular basis associated with the etiopathogenesis of these neoplasms. We review the literature on cytogenetics, familial syndromes, animal models and molecular genetics of pineal region neoplasms.
