Some tumors are unique because they come from residual embryonic as kraniofaringioma, derived from Rathke pouch: Dermoid and epidermoid tumors derived from epithelial cells during invagination of neural tube closure, and kordoma, which evolved from the legacy of the embryonic notochord. The pathogenesis of brain tumors is complex, since it only complains about the factors that mcmpengaruhi development. Circumstances arising as a result of impaired development of the nervous system comb has a strong relationship with the tumor SSS.
