Pituitary dwarfism in a dog

Abstract

Clinical and pathologic alterations in a one year and half old German shepherd male dog with pituitary dwarfism were described. Lethargy, small stature, puppy coats of lanugo hair, oppened epiphysis, alopecia and hyperpigmentation of skin, spastic paralysis of the distal limbs and pryapism were the clinical abnormalities observed during, the four months period of observation. Cystic formations filled with eosinophylic material and replacing partially pituitary gland, thyroid and adrenal hypoplasia were the most proeminent pathologic and histopathologic features. The probable origin of the ciliated columnar epithelium that lined the cysts were discussed.
