Core Tip
Core tip: Basaloid squamous carcinoma (BSC) is a rare variant of esophageal cancer. In our case, narrowband imaging magnified endoscopy (NBI-ME) findings differed from those observed in typical squamous cell carcinoma in that non-invasive cancer-like irregular loop-shaped microvessels coexisted with massively invasive cancer-like thick non-looped vessels. We speculate that the looped and non-looped vessels observed by NBI-ME histologically corresponded to thin vessels in the intra-epithelial papilla and thick vessels around the tumor nests, respectively. These NBI-ME findings might be a feature of early BSC. To our knowledge, this is the first report in the English literature describing the NBI-ME findings of BSC.
