Ultrastructural features of the interferon-treated adult laryngeal papilloma.
The ultrastructural features of the interferon-treated adult laryngeal papillomas are described. Compared with untreated papillomas, no differences in ultrastructure were found by transmission electron microscopy. By scanning electron microscopy, significant alterations comprising a smooth and oedematous surface with a uniform microvilli pattern of the superficial cells were observed after interferon therapy. Our observations suggest an increased cell adhesion and maturation of epithelial cells caused by interferon.
