Narrow‐band imaging ( NBI ) has been reported to be useful for detecting superficial‐type esophageal or head and neck squamous cell carcinoma ( SCC ), and in the present study we have used  NBI  to detect non‐carcinomatous lesions, such as basal cell hyperplasia ( BCH ) accompanied by microvascular irregularities; these non‐carcinomatous lesions were pathologically discriminated from squamous cell carcinoma of the pharynx. The aim of the present study was to clarify the endoscopic characteristics of  BCH  that contribute to the discrimination of superficial‐type head and neck  SCC  ( HNSCC ). We examined the key endoscopic findings capable of distinguishing  BCH  from  SCC  using 26  BCH  and 37 superficial‐type  SCC  of the pharynx that had been pathologically diagnosed at our institution between January 2008 and July 2012. 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. This study revealed that  BCH  was an independent entity in terms of not only pathological findings, but also endoscopic findings observed using  NBI , such as the regular distribution of  IPCL  and the preserved intervascular transparency.
