Squamous cell papilloma of esophagus is a very rare benign tumor. It is reported with increasing frequency recently. The lesion is small and diagnosis is often fortuitous. The etiology remains unknown. Grossly, on endoscopy, the papilioma appears as a smooth, round, pink, sharply demarcated, sessile tumor projecting from the esophageal wall. Histologically, the squamous papillomas are benign sessile lesions of surface epithelium, characteristically composed of finger-like projections of tissue, lined by an increased number of squamous cells. The average age range is 6th decade, men outnumber women almost two to one, most are distal in location, and symptoms are diverse. We observed 2 cases of squamous cell patilloma of esophagus. Our purpose here is to report these cases and review the literatures.
