Successful Treatment of Extensive Esophageal Squamous Papillomatosis With Cryotherapy.

Esophageal squamous papilloma is a rare endoscopic finding, and esophageal squamous papillomatosis (ESP) is considered exceptionally rare, with only a limited number of cases reported to date. There is a paucity of literature about the management of these lesions, and it remains largely controversial. We report a 61-year-old man who presented for endoscopic treatment of ESP detected during endoscopic evaluation for heartburn. Given the potential risk of malignant transformation, a decision was made to proceed with spray cryoablation, requiring a total of 3 sessions of ablative therapy. The histopathological assessment confirmed the diagnosis, and the specimens tested negative for all low- and high-risk human papillomavirus subtypes. Follow-up endoscopies revealed near-complete resolution. To our knowledge, the present report describes the second successful treatment of ESP using endoscopic spray cryotherapy.
