The squamous papilloma of the esophagus is a rare disease.

The pathogenesis and biological features of the disorder are not clearly known.

Markers of human papilloma virus infection have been found in some cases. Role of the virus in the pathogenesis of the tumor is not known.

Some authors have suggested an association with GERD others support  the hypothesis that mucosal injury and regeneration underlies the etiology of esophageal squamous cell papilloma formation.

Site-  Lower third of the esophagus

Gross- Usually less than 1.5 cm in maximum diameter. Single, sessile, well circumscribed, intraluminal nodule. In about 10% of cases, the tumors are multiple .

Microscopic feature-

Papillary lesion lined by hyperplastic squamous epithelium with a fibrovascular connective tissue core.

Koilocytosis and multinucleation may be present indicating viral origin.
