[Granular cell tumor of the esophagus].

Granular cell tumor is a relatively rare, mostly benign lesion, that can be found in almost every organ, however, only 2% of the cases is oesophageal. It is named after the eosinophilic S-100 protein positive granula in the cytoplasm of the tumor cells. Since patients with oesophageal granular cell tumor are mostly symptomless, the tumor is usually found accidentally. Even in patients with dysphagia, contrast radiograph and gastroscopy show an atypical picture, therefore, the diagnosis is based on the histological examination. Therapy is usually conservative, but surgical treatment might be necessary sometimes. A patient with severe dysphagia is reported here. She was diagnosed with a granular cell tumor in the oesophagus, and the tumor was surgically removed.
