Sellar masses, pituitary adenomas and pathways of pituitary tumourigenesis

垂体瘤包括许多病理。他们的理由并不明确。垂体腺瘤是最常见的颅内肿瘤之一。散发性肿瘤的遗传学是未知的。颅咽管瘤是一种罕见的脑肿瘤，发生在垂体柄区域，可产生深远的影响，在儿童或以后出现。到目前为止，对导致这些肿瘤的细胞信号通路的了解有限，这有助于了解癌症。

Pituitary tumours encompass a number of pathologies. Their cause is not clearly established. Pituitary adenomas are one of the most frequent intracranial tumours. The genetics of sporadic tumours is unknown. Craniopharyngiomas are rare brain tumours arising in the pituitary stalk area that can have profound effects, presenting in childhood or later. To date there is limited knowledge on the cell signaling pathways causing these tumors, which can help to understand cancer in general.
