ABSTRACT
Benign ductal or glandular neoplasms of the esophagus unrelated to Barrett esophagus are extremely rare. Only 9 cases have been reported in the English language literature. We now report a case of esophageal gland duct adenoma incidentally found in a 73-year-old man. A 0.8 cm-sized, polypoid submucosal lesion in the distal esophagus was removed. Histologically, the lesion was well circumscribed and consisted of several ducts or cysts with focal papillary configurations. Interstitial lymphocytic infiltration with germinal centers was also observed. The lining cells of ducts or cysts were composed of two layers an inner intensely eosinophilic luminal duct cell layer and an outer myoepithelial cell layer that was accentuated by alpha-smooth muscle actin. There was no significant nuclear atypia or mitosis. Mucin production was occasionally observed in a few goblet cells. To the best of our knowledge, this is the first case of benign ductal or glandular neoplasm of the esophagus among Koreans.
