Esophageal cell tumors are rare. Esophagogastroduodenoscopy performed on a 48-year-old woman revealed an elevated esophageal lesion and the presence of long-segment Barrett's esophagus. Endoscopic ultrasonography showed a 15 mm homogeneous hypoechoic tumor extending from the lamina propria mucosa to the submucosa. ⋯ The tumor was resected by endoscopic submucosal dissection. Pathologically, the background mucosa was Barrett's mucosa. This is the first reported case of an esophageal granular cell tumor in long-segment Barrett's esophagus.

Review Case Reports
A Significant Increase in the Serum Carbohydrate Antigen 19-9 Level Accompanied by Acute Cholecystitis and Choledocholithiasis: A Case Report and Review of the Literature.
An 80-year-old man with jaundice and fatigue was referred to our hospital. A laboratory examination revealed increased levels of hepatobiliary enzymes, and CA19-9 levels increased to 29,512 U/mL. Based on the findings of imaging examination and laboratory data, the patient was diagnosed with acute cholecystitis and choledocholithiasis. ⋯ Antibiotic administration was commenced, and the common bile duct stone was endoscopically removed. One month after treatment, the CA19-9 level decreased to within the normal range. One year after treatment, imaging examinations did not reveal any malignancy.
