Summary:See PDF.] a Blue laser imaging of a Prague C3M4 Barrett’s esophagus with a tongue highlighted at 3 o’clock. b An estimated 20-mm nodular ulcerated lesion emerged at the gastroesophageal junction (c) as replicated on retroflexed LCI visualization. d LCI after acetic acid spraying in the distal esophagus highlighted another 8-mm flat lesion with an irregular vessel and surface pattern consistent with early cancer. Barrett´s esophagus is a well-acknowledged risk factor for esophageal AC formation; however, singular cases of SCC arising in Barrett’s esophagus and/or collision tumor comprising SCC and AC elements have been documented in the literature, pointing to ambivalent carcinogenic field effects [1‒3]. Conflict of Interest Statement The authors have no conflicts of interest to declare.
