Rathke Cleft Cyst with a Coexisting Gonadotropin Producing Pituitary Adenoma
Rathke cleft cyst is thought to arise from incomplete obliteration of the lumen of Rathke pouch. The cells of the anterior pituitary lobe, from which pituitary adenomas develop, are also derived from the cells of Rathke pouch. Although Rathke cleft cyst and pituitary adenoma have a shared ancestry, they rarely occur coincidentally. Rathke cleft cysts have been found incidentally in 11% 33% of p...
متن کاملThe Morphology and Pathology of the Pharyngeal Pouch of Rathke
The pharyngeal pouch or bursa pharyngea was first described by Rathke in 1838.1 It is now a place of great interest both to the surgeon and to the scientist: here post-nasal adenoids have their birthplace, and probably the oesophagus has its ancestry. The pouch of Rathke is a tubular recess at the upper and posterior wall of the pharynx, not at all infrequent in the adult, commoner in children,...

The urgent symptoms which frequently result from compression of the optic nerves and chiasm have focused attention upon themselves so that some of the manifestations of adrenal cortical insufficiency secondary to " pituitary tumour " have received scant notice. This is not to say that they are totally unknown, but they form a submerged body of knowledge to which relatively little importance is ...
متن کاملDirect and indirect requirements of Shh/Gli signaling in early pituitary development.
Induction of early pituitary progenitors is achieved through combined activities of signals from adjacent embryonic tissues. Previous studies have identified a requirement for oral ectoderm derived Sonic Hedgehog (Shh) in specification and/or proliferation of early pituitary progenitors, however how different Gli genes mediate Shh signaling to control pituitary progenitor development has not ye...
