Abstract
We treated a minute, submucosal, invasive squamous cell carcinoma of the esophagus. The patient was a 63-year-old man. On routine endoscopy ared ared was seen, and the surface seemed to be slightly depressed in the central part of the lesion. A small, white elevation was noted around the lesion. On routine examination using more advanced endoscope, color changes and minute changes of small vascular network were clearly recognized. EMR was done. On histopathology a mucosal defect was seen in the central part of the lesion. The small lesion was approximately 4mm in size. Carcinomatous invasion had destroyed the muscularis mucosa and extended to the submucosal layer (sm 1 cancer). This case is being reported due to the rarity of minute submucosal invasive squamous cell carcinoma of the esophagus.
