Esophageal tumors are considered a rarity in present day diagnostic interpretations, however, a report from Alabama indicates that such tumors are by no means so rare as have been the indications. In a series of esophageal neoplasms found in dogs over a period of 3 years the esophageal worm, Spirocerca lupi, was found in each tumor. This may possibly indicate the etiological importance of the parasite.
