초록

A pulmonary keratinizing cyst was found incidentally in a 30-week-old female Sprague-Dawley rat. The cyst was lobe of the lung, lined by stratified squamous epithelium and filled with concentric layers of desquamated keratin. The wall consisted of 2-4 layers of well differenciated squamous cells. The adjacent lung tissues were slightly compressed but not otherwise damaged by the cyst. There was no inflammatory reaction or mitotic figures observed in the cyst.
