Verrucous carcinoma of the esophagus: A potential diagnostic dilemma

Abstract

Verrucous carcinoma of the esophagus is a rare variant of squamous cell carcinoma associated with human papillomavirus. We report the case of a 58-year-old female who presented with ongoing symptoms of dysphagia. On previous endoscopies she had been noted to have a large polyp-like mass involving the esophagus, with negative biopsies for malignancy. Repeat endoscopy with concurrent endoscopic ultrasound showed a large semi-pedunculated polyp in the distal esophagus and a hypoechoic, irregular mass involving the gastroesophageal junction with esophageal thickening. Deep layer biopsies showed pseudoepitheliomatous hyperplasia with immunohistochemical staining positive for human papillomavirus. The patient was subsequently treated with chemo-radiation followed by esophagectomy.
