title: Squamous papilloma of the esophagus: report of six cases with long-term follow-up in four patients.
abstract: Squamous papilloma of the esophagus is a benign tumor. The diagnosis is usually made accidentally when an upper gastrointestinal endoscopy is performed due to upper abdominal or esophageal symptoms. After having reviewed 14,900 upper gastrointestinal endoscopies during the past 8 yr, we report six additional cases of esophageal squamous papilloma. The lesion seems to be relatively quiescent without apparent malignant changes, at least on a short-term basis. The etiology is unknown; however, we conclude that gastroesophageal reflux may predispose to the lesion and that endoscopic follow-up on these patients may be unnecessary due to the benign nature of the lesion.
