Post-transplant Amputation Traumatic Neuroma of the Hilum and Extrahepatic Duct in a Liver Donor

Abstract

Traumatic neuromas develop after injury to nerve fibers encased in Schwann cells. They occur mainly in the amputated stump of the extremities.(1) Biliary traumatic neuroma was first described in 1928 by Husseinoff.(2) Since then, less than 100 cases of biliary traumatic neuroma have been reported.(3,4) Most occur at the cystic duct stump after cholecystectomy. It may also occur in the main biliary tract following any injury, even liver transplantation.(5,6) Herein, we report a case of post-transplant biliary traumatic neuroma in a donor after an 8-year interval. This rare biliary traumatic neuroma may be a risk factor for liver transplantation-related biliary stricture.
