Spi·ro·cer·ca lu·pi

(spī'rō-ser'kă lū'pī),
The esophageal worm of dogs and other carnivores, a red spiruroid nematode that occurs in nodules in the wall of the esophagus, stomach, and aorta of dogs, foxes, and wolves; intermediate hosts are various coprophagic beetles. Clinical symptoms occur only in very heavy infections, which are associated with esophageal carcinomata in dogs and with hypertrophic pulmonary osteoarthropathy.

The nodules may be large enough to cause obstruction of the esophagus and the aorta. The esophageal lesion converts to a fibrosarcoma or an osteosarcoma in a number of cases.
