Esophageal Squamous Papilloma Associated with Human Papillomavirus

Abstract

Esophageal squamous papilloma (ESP) is a rare benign tumor of the esophagus. Human papillomavirus is known to infect the genitourinary tract, the anal canal, the respiratory tract, and the skin. It is associated with benign, precancerous and cancerous lesions. Esophageal papillomas, including HPV-induced squamous cell papillomas of the esophagus, are rare, with an incidence ranging from 0.01 to 0.04 percent. We present a case of esophageal HPV induced squamous cell papilloma. A 59-year-old male presented to the clinic with epigastric abdominal pain radiating to the chest, he was treated empirically with Pantoprazole with the resolution of symptoms. The patient underwent Positron Emission Tomography (PET) scan as part of follow-up surveillance for stage IV adenocarcinoma of the lung that was resected two years ago, it showed hypermetabolic focus involving the gastroesophageal junction. Biopsy of the lesion was consistent with the involvement of human papillomavirus with no evidence of dysplasia. This case illustrates the recognizing the role of human papillomavirus in squamous cell papilloma of the esophagus and its association with GERD.
