[Abrikossof tumor in the esophagus].

Among the benign tumours of the oesophagus, the discovery of an Abrikossof tumour is exceptional. Although modern methods of investigation now permit recognition of this tumour and suspect its benign nature, only histology permits one to determine its precise nature, either by biopsy or by frozen section. Histogenetically, the schwann cell and histiocytic theories are not completely incompatible to the extent that they are considered from the point of view of general pathology, where there is evidence in favour of the mesoectodermic origin of the granular cell myoblastomas. In all cases, surgical excision is necessary. This resection of the myoblastoma permits a permanent cure.
