Endoscopic findings using narrow-band imaging to distinguish between basal cell hyperplasia and carcinoma of the pharynx.

Yagishita A, Fujii S, Yano T, Kaneko K - Cancer Sci. (2014)

Bottom Line: The clinicopathological factors were also compared.The size of the BCH lesions was significantly smaller (P < 0.001), and their intervascular transparency was more clearly observed (P < 0.001).Intra-epithelial papillary capillary loop (IPCL) shapes were less variable and monotonous (P < 0.001), and the distribution of the IPCL was more regular with an interval comparable to that of SCC (P < 0.001), although no significant differences in the sharpness of the lesion border, dilatation of IPCL and tortuosity of the IPCL were seen between the BCH and SCC lesions.

Mentions: For further understanding and clinical use, we have presented the images of a case with stepwise magnification in a schema shown in Fig. 3. An endocytoscope is not indispensable, but is helpful for understanding the features of BCH and SCC. In daily clinical situations, it may be difficult to magnify the pharynx adequately because of the gag reflex or the lack of magnifying endoscopes at some institutes. Even if it is impossible or difficult to magnify the images, the evaluation of intervascular transparency alone should be helpful, to some extent, in making a differential diagnosis.
