normal mucosa
lymphoid hyperplasia
nasopharyngeal carcinoma
Flat and relatively uniform polygonal epithelial cells with alternating dark and light bands were noted in pCLE images of normal mucosa after intravenous injecting 10% fluorescein.
An unorganized tissue architecture, irregular cells (difference of cell shape, color and size), slightly intensified fluorescein leakage, and vessels not assessable were found in the lymphoid hyperplasia of nasopharyngeal mucosa after intravenous injecting 10% fluorescein..
pCLE images of nasopharyngeal carcinoma, which was associated with crowded unorganized tissue architecture (a dark-gray background without identification of mucosal structures), irregular cells like cell clusters, amplified fluorescein leakage, and irregular vessels changes after intravenous injecting 10% fluorescein.
