中倍镜和高倍镜示颅咽管瘤


中倍镜和高倍镜示颅咽管瘤,起源于Rathke'S囊并且在蝶鞍处形成膨胀性的大肿块,侵蚀骨并浸润周围的组织结构。尽管在组织学上由鳞状上皮和柱状上皮构成囊腔,囊内充满脂性液体,但难以根除。

A craniopharyngioma is seen here at medium and high power. It is derived from remnants of Rathke's pouch and forms an expanding mass arising in the sella turcica that erodes bone and infiltrates into surrounding structures. They are difficult to eradicate, even though they are composed of histologically appearing squamoid and columnar epithelium lining cystic spaces filled with oily fluid.
