title: Update on desmoid tumors.
abstract: Desmoid tumors (DTs) are histologically benign proliferations of stromal cells but may grow locally aggressive. Overall, DTs are rare (0.03% of all neoplasms). A minority of DTs is associated with Gardner syndrome and mutations of the familial adenomatous polyposis (FAP) gene. Most spontaneous DTs are associated with mutations of the beta-catenin gene. This mutation results in the activation of Wnt/catenin signaling. Due to their variable clinical presentation and behavior, no standard approach for DTs can be recommended. In most cases of DTs of the extremities surgical extirpation is indicated, whereas in many other cases, a multimodal and multidisciplinary concept should be followed. In this review article, we discuss the diagnosis, pathogenesis, and treatment options for DTs, including targeted therapy with tyrosine kinase inhibitors.
