Clinicopathological characteristics of patients with oesophageal squamous papilloma in Turkey and comparison with the literature data: The largest case series ever reported from Turkey.

In this study with the largest case series ever reported from Turkey, it was determined that ESPs were seen in younger ages in Turkey and were also smaller in size, which is not in agreement with the literature data. Besides, this study, in which ESPs were most frequently detected in the middle oesophagus, supports the view that GERD may not be the main factor in ESP aetiology.
