[Abrikossof's tumor of the esophagus. An original case. Review of the literature].

Granular-cell tumors (GCT), also called Abrikossof's tumors, are generally benign, ubiquitous tumors. An original case of granular-cell tumor of the esophagus is reported. The symptoms included dysphagia and pyrosis. Fiberendoscopy showed a peptic esophageal stenosis with ulcerations confirmed by biopsy. CT showed a round thickening of the esophageal wall, localized in height. This lesion had previously been the object of several dilatation attempts. Esophagectomy with esogastric anastomosis in the thorax was performed. The histological study allowed diagnosing a granular-cell tumor, though one of a very peculiar type: misleading symptoms, tumor infiltrating the whole height of the esophagus and a circular area. Ninety cases of granular-cell tumors are reported in the literature; they are associated with a cancer of the air passages or of the digestive tract in 11% of cases. The cancer often appears secondarily, which requires lengthy surveillance. We do not know if this association is directly related or accidental. We have found no identical case of such a lesion, involving both the whole circumference and the whole height of the esophagus, in the literature.
