Pituitary Gland - Cyst in a female Harlan Sprague-Dawley rat from a chronic study. A cyst filled with pale eosinophilic proteinaceous fluid is present in the pars distalis.
Pituitary Gland - Cyst in a female Harlan Sprague-Dawley rat from a chronic study. Higher magnification of Figure 1 shows that the cyst is partially lined by tall cuboidal ciliated epithelium.
Pituitary Gland - Cyst in a male F344/n rat from a chronic study. The cysts in the pars distalis are lined by ciliated cuboidal cells and contain flocculant eosinophilic proteinaceous material.
Pituitary Gland - Cyst, multiple in a female F344/N rat from a chronic study. Multiple cysts are present in the pars nervosa (arrows), as well as a dilated persistent Rathke�s cleft (asterisks), are filled with eosinophilic proteinaceous material.
