A cartilaginous choristoma in a pig liver: A case report

Abstract

Choristomas are small aggregates of normal tissue components in aberrant locations, and may be mistaken for true neoplasms. We report a case of an incidentally found mature cartilage island in the portal tract of a two-month old piglet. All other examined organs were normal. The pig belonged to the control group of animals in a short-term experiment, was fed with wheat and corn, and did not receive any external or internal treatment. To the best of our knowledge, this is the first case of a mature cartilaginous choristoma in pig liver.
