Pancreatic Choristoma in a Canine Gallbladder

Publication date: January 2019Source: Journal of Comparative Pathology, Volume 166Author(s): Y. Abou Monsef, S. Atalay Vural, O. KutsalSummaryA 1.5-year-old male Siberian Husky dog was presented with a history of progressive twitching and tetraplegia. The dog was humanely destroyed and at necropsy examination an incidental intramural white lesion measuring 10 × 15 × 5 mm was observed in the gallbladder. Histologically, the mass consisted of pancreatic tissue located in the tunica adventitia of the gallbladder. Immunohistochemistry revealed that the islets of Langerhans were positive for insulin, but negative for glucagon. In addition, the dog had non-suppurative meningoencephalitis associated with canine distemper virus infection. The gallbladder lesion was consistent with pancreatic choristoma and is the first case described in a canine gallbladder.
