Abstract
A 23-year-old woman was referred for a gastroscopy. She had a long history of upper abdominal pain, pyrosis and postprandial fullness without a complete response to proton-pump-inhibitors. She didn’t relate any other rele- vant symptom or antecedent. Routine blood analysis re- vealed no abnormalities.
The exam was made with a confocal endomicroscope (Pentax EPK-1000, ISC-1000). White light examination found a small flat orange mucosal islet in the cervical esophagus adjacent to the upper esophagic sphincter. It had a diameter of approximately 30mm and beside it there was a 2mm satellite islet. The rest of the exam was normal. The islets were explored with CE after intra- venous injection of 5 mL fluoresceine as a contrast agent. It provided images of small glands with round luminal openings and polygonal epithelial cells with cobblestone appearance distinctive of gastric mucosa. Intestinal meta- plasia was ruled out since no goblet cells were visualized. The regular architecture of glandular epithelium and the microvasculature as well as the absence of a strong fluo- resceine leakage indicated a benign process (figure 1).
