Fibromatosis of the mesoappendix

Abstract

Mesenchymal tumors of the appendix are very rare. Mesenteric fibromatosis is the most common diagnosis in the case of isolated proliferative fibroblastic lesion found in this region. However, the differential diagnosis between fibromatosis and well-differentiated fibrosarcoma (Grade I) can be difficult in some borderline cases. A rare case of proliferative fibroblastic lesion involving the appendix and mesoappendix is presented, and its origin, diagnosis and differential diagnosis are discussed.

Mesenteric Fibromatosis: A Case Report

“…Mezenterik fibromatoziste prolifere fibroblastlar mevcuttur ve benign reaktif fibrozisten sınırlarının infiltratif özellik göstermesiyle ayrı-lırlar. Ancak bazı durumlarda iyi differansiye fibrosarkomlardan ayrımı güç olabilir [18]. Pleomorfizim ve mitotik aktivite fibrosarkomlardan ayırmada kullanılacak parametrelerdir [17].…”
