White granular sensation on the raised surface of the esophagus may be caused by esophagitis or esophageal tumors, which need to be diagnosed by pathological biopsy. 1. Esophagitis: for example, white granular sensation may appear when infected with fungal esophagitis, burning sensation under the sternum and foreign body sensation in the throat. 2. Esophageal tumor: white granularity can be seen in this kind of people, and occupying tumors can also protrude into the lumen, which need to be determined by pathological biopsy to see whether there are cancer cells, and if there are no cancer cells, it is usually a benign lesion, and surgical resection can be done. It is recommended to go to the hospital for consultation and confirm the diagnosis through esophagoscopy and pathological biopsy in time.
