Squamous mucosal alterations in esophagectomy specimens from patients with end-stage achalasia.
Abstract
Achalasia is an esophageal motor disorder in which the primary morphologic changes are found in the myenteric plexus. However, a number of secondary alterations are characteristically found in esophagectomy specimens, including the mucosa. In addition, these patients are at increased risk of developing esophageal squamous cell carcinoma. We studied the squamous mucosal alterations in 35 esophagectomy specimens from patients with end-stage achalasia and compared them with those found in the squamous mucosa near the esophagogastric junction from pediatric autopsies (
