RESUMO
The granular cell tumor was first described in 1926. Recently, it has been suggested that the tumor is Schwann cell in origin, and this notion has been supported by electron microscopic studies and immunohistochemistry of the S-100 protein. The most frequently involved organs include the tongue, skin, breast, and digestive tract. The esophagus is rarely involved. The treatment of choice for an esophageal granular cell tumor is still controversial. The traditional treatment has been surgical excision, but new therapeutic options, including laser surgery, diathermy loop, and multiple biopsies have recently been tried. An endoscopic esophageal mucosal resection (EEMR) tube, originally designed for resection of early esophageal cancer, is widely used nowadays. A case of a granular cell tumor of the esophagus, which was successfully removed by an EEMR tube, is herein reported.

Plummer-Vinson syndrome is characterized by dysphagia associated with anemia, glossitis and esophageal web. The cause of this syndrome is still not clear, but the most important one is thought to be the iron deficiency. The patient with small sized ageal web is treated by administration of iron but large sized web with dyspha gia requires breakage of web. In the following case report, we describe a patient with Plummer-Vinson syndrome who showed clinical improvement after treatmeat with endoscopic balloon dilatation of upper esophageal web with a review of literatures.
