mesenteric desmoid fibromatosis
Thursday 10 January 2013
Definition: Desmoid-type fibromatosis (desmoid) is a fibroblastic tumour that shows locally aggressive growth. Mesenteric desmoid is a rare lesion that shares morphological and biological features with fibromatoses occurring in the abdominal wall or in extraabdominal sites, but differs in terms of gross appearance and clinical presentation.
β-Catenin-negative desmoids either carried a CTNNB1 mutation or are associated with Gardner syndrome.
Some clinical and genetic features of mesenteric desmoids differ from those of non-mesenteric fibromatosis, and corroborates the usefulness of mutational analysis, especially in diagnosing β-catenin-negative mesenteric desmoids.
