Identification of Familial Adenomatous Polyposis carriers among children with desmoid tumours.

Objective: Desmoid tumours are rare mesenchymal tumours with unpredictable progression and high recurrence risk. They can occur sporadically or in association with Familial Adenomatous Polyposis (FAP), which is caused by germline APC mutations. The Wnt/β-catenin pathway has a central role in the pathogenesis of desmoid tumours.

A 62-year-old man with alcoholic liver cirrhosis underwent liver transplantation. The transplantation went uneventful and the ultrasound imaging of the liver performed after transplantation did not show any abnormalities. Eighteen months later, an intra-hepatic focal lesion was found on ultrasound.
