Multiple adenomatous neoplasms arising in columnarlined (Barrett's) esophagus
Abstract:
Multiple polypoid masses were found in the esophagus of a 62-year-old man. He underwent esophageal resection because exfoliative and brush cytological studies were positive for adenocarcinoma. The surgical specimen showed that the esophagus was lined by columnar epithelial cells which were focally hyperplastic, forming polypoid masses. In both the masses and the mucosa between them, there were atypical epithelial cell changes, ranging from dysplasia to focal carcinoma. These findings reinforce the concept that the Barrett's (columnar) epithelium is a premalignant lesion deserving periodical screening.
