From: Sporadic intra-abdominal desmoid tumor with a very unusual onset: two case reports
Histological and immunohistological features of desmoid tumors in Case 2. a Hematoxylin and eosin (HE) staining shows proliferation of spindle-shaped cells. Wavy collagenous bands of fiber lie in stroma (low-power view). b Immunohistological staining for β-catenin shows strongly positive staining of cell (high-power view). c Immunohistological expression of Ki67 in tumor. Labeling index =1% (high-power view)
