Adenocarcinoma in a Barrett oesophagus

A case of adenocarcinoma developing at the squamocolumnar epithelial junction of a Barrett oesophagus is reported. This rare tumour was remarkable because of the youth of the patient and because of the signet-cell cytological pattern of the neoplasm. It is postulated that both the columnar epithelial lining of the lower part of the oesophagus and the malignant change are a consequence of long-standing oesophageal reflux.
