Finding a lymphangioma in the upper digestive tract is a rather infrequent event. A case of a 64-year-old man is reported. Diagnosis was made in the course of an endoscopic oesophagogastroduodenal examination and tumor excision with a diathermy snare at the same time. Two years after resection there was no sign of recidivation of the tumor. © 1979, Georg Thieme Verlag, Stuttgart. All rights reserved.
