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.
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.
