Figure 1

Macroscopical and microscopical features of her second time abdominal wall mass resection. (a and b) Abdominal lesions, macroscopically, the surface of the tumor was white-tending to brown, with varying amounts of hemorrhage and necrosis. Microscopically, the lesion displayed infiltrative hyperplasia in the abdominal adipose fibrous tissue (c and d, H&E, ×10). IHC showed moderate staining for CK (e ×40), MEL-CAM (f ×40), and HPL (h ×40), focally positive for HCG (g ×40). The Ki-67 proliferative index was about 20% (i ×40).
