Larsen, G. L., Armstrong, R. G., Stanford, W., and Cline, R. E. (1973).Thorax, 28, 641-643. Granular cell myoblastoma of the oesophagus. During evaluation of symptoms of oesophageal reflux in a 40-year-old man, a filling defect of the distal oesophagus was seen on the oesophagogram, and this was noted to be a submucosal mass at oesophagoscopy. He also had an oesophageal hiatus hernia. The lesion proved to be a granular cell myoblastoma, a rarity in the oesophagus, only 11 previous cases having been reported. Symptomatology evaluation and management of granular cell myoblastoma of the oesophagus are discussed. As with other submucosal lesions of the oesophagus, preoperative biopsy through an intact mucosa is to be avoided because of danger to the patient from haemorrhage or perforation and subsequent inflammatory reaction making surgical resection and microscopic diagnosis difficult.
