Their most frequent symptoms are dysphagia and epigastric or retrosternal discomfort. We here report a case of esophageal GCT with continued symptoms of retrosternal discomfort, postprandial feeling of fullness, and early satiety despite complete thoracoscopic resection of the tumor. In contrast, all functional tests were in the normal range. We thus suggest that, due to their neuroectodermal origin, GCTs may affect neuronal alterations leading to a persistently disturbed visceral mechanosensory perception. Consequently, this case also cautions the therapeutic concept to solely relieve GCT symptoms by resection if the tumor is less than 20 mm in diameter.en© Karl Demeter Verlag im Georg Thieme Verlag StuttgartAbrikosov's tumorEndosonographyFunctional gastrointestinal disordersGranular cell tumorMyeloblastic myomaVisceralmechanosensory perceptionJournal article002009372810.1055/s-2003-418262-s2.0-014163384436809
