We recently found three cases of squamous cell papilloma of the esophagus. The first case was a 65-year-old-male who had been detected to have a movable mass at the lower esophagus by the upper G-I series. On endoscopy after admission, a pedunculated mulberry-like tumor with a marked reddish surface was detected on the right dorsal side of the lower esophagus. Polypectomy was performed and the size was 16×13×5mm. Histologically, proliferation of squamous cells with marked papillary growth and partial keratinization was observed on the surface and the tumor was diagnosed as squamous cell papilloma. The second case was a 71-year-old-male who was hospitalized due to hypothyroidism. After admission he showed positive occult blood in the stool and endoscopy detected a 5 mm flat and whitish mass on the ventral side of the lower esophagus. Biopsy was performed and the histological finding was similar to that of the former case and the diagnosis was squamous cell papilloma. The third case was a 64-year-old-male who had been detected an abnormal defect shadow by the upper G-I series due to the chief complaint of epigastric pain. After admission, endoscopy revealed a mulberry-like tumor on the ventral side of the lower esophagus. Polypectomy was performed and the histological diagnosis was squamous cell papilloma. Squamous cell papilloma of the esophagus is a very rare disease and only 25 cases including the present ones have been reported in Japan.
