Adenosquamous carcinoma in Barrett's esophagus presenting as pseudoachalasia

Abstract

A case of pseudoachalasia resulting from adenosquamous carcinoma arising from the mucous epithelium of a Barrett's esophagus is presented. This case represents an unusual combination of Barrett's esophagus giving rise to an esophageal carcinoma with squamous as well as glandular features, rather than the usual adenocarcinoma and pseudoachalasia.
