[A histochemical study of the glandular system of the human epiglottis. The clinical implications].
The paper deals about classical histologic and histochemical study for mucinoid substances through 7 laryngeal pieces coming from clinic autopsies. The gland units occurring in the two lower thirds of the epiglottis were formed by a great number of serous acini and mucinous tubuli, which secretion is acid and neutral mucous substances, as sialomucins, serving as lubricant and protective means. This glandular system convey through the epiglottic perforans holes, without break, the pre-epiglottic and epiglottic spaces, with the clinical repercussion that suggest the chance of encroachment for incipient epiglottic cancer to pre-epiglottic room.
