[Granular-cell tumor of the stomach and esophagus]. / Granularzelltumor des Magens und Osophagus.

A 45-year-old man had for the past four years complained of postprandial feeling of fullness and of left-thoracic pressure sensation. Endoscopy revealed a spherical subcardial tumour, about 3.5 cm diameter, a yellow raised flat 7 x 4 mm tumour in the oesophagus about 44 cm from the upper teeth, and 29 cm from the upper teeth a 4 mm bulge. Forceps biopsy of the subcardial tumour and fine-needle biopsy of the rather larger oesophageal tumour indicated a granular cell tumour. Because of the risk of malignancy the gastric tumour was resected (local excision and fundal plication). The patient has remained without symptoms for 28 months. Follow-up endoscopies have demonstrated that the oesophageal tumours had not grown any further.
