Report of a case with small bowel obstruction by a rare parasite [Pentastomiasis]

Linguatula serrata [L. serrata], an aberrant arthropod of the Pentastomida phylum, inhabits the canine respiratory system as its final host. Intermediate hosts include humans and herbivores. Humans can be infected via consumption of raw or under-cooked liver or lymph nodes of sheep, goats, and cattle. A few human cases have been reported from Iran.
