From: Intra-abdominal desmoid tumor mimicking gastric cancer recurrence: a case report
Pathologic features of the desmoid tumor. (a) Macroscopically, a 40 × 30 × 30 mm hard elastic tumor was seen in the mesentery of the transverse colon. The cut surface is whitish and poorly circumscribed with surrounding adipose tissue. (b, c) Histologically, proliferation of spindle-shaped cells with collagenous stroma is seen (hematoxylin and eosin staining; b: low-power field, c: high-power field). (d) Immunohistological examination revealed that the cell nuclei were positive for beta-catenin.
