[Esophageal squamous cell papilloma. Report of 3 cases. Diagnostic aspects].
Dysphagia is not always present in patients with esophageal squamous cell papilloma, and it can be an incidental finding during gastrointestinal endoscopy of an asymptomatic patient.


OBJECTIVE
Three cases of squamous cell papilloma of the esophagus and aspects regarding diagnosis and association with human papillomavirus are presented. CASUISTIC: Two cases are male and one female what is consistent with a higher incidence showed in the literature in males. The three patients were submitted to upper gastrointestinal endoscopy: in one case the tumor was unusually large and in all patients it was located in the mid and lower esophagus. Chromoscopy was performed in one case and the lesion was not stained. We were unable to identify human papillomavirus using DNA-hybridization techniques. Our results are similar to those reported in the review of the literature.


RESULTS
There is no other case published in the Brazilian literature and this is the first report on the use of chromoscopy.


CONCLUSIONS
We were not able to show an association between esophageal squamous papilloma and human papillomavirus.
