[Epidemiology, Genetics and Pathophysiology of Pituitary Tumors].

Pituitary tumors or tumors of the sella turcica include pituitary neuroendocrine tumors, Rathke's cleft cysts, craniopharyngiomas, tuberculum sellae, planum sphenoidale meningiomas, germ cell tumors, and hypophysitis. In addition, some rare tumors, such as pituicytomas, granular cell tumors, spindle cell oncocytomas, and chordomas or chondrosarcomas, arise from the parasellar regions. The treatment strategy is completely different for each lesion; therefore, accurate diagnosis is essential.
