Pylorus-preserving pancreaticoduodenectomy specimen and liver metastasis after neoadjuvant treatment showing major histopathological response (14): (A) pancreatic tissue with dense fibrosis and single groups of residual tumor/carcinoma cells (HE, obj.-magn. 20×). (B) Residual tumor cells, higher magnification of A (obj. magn. 40×). (C) Micrometastasis to a regional peripancreatic lymph node (Obj.-magn. 10×). (D) Complete tumor regression of a liver metastasis with necrosis, fibrosis and no residual cancer cells (HE, obj.-magn, 1×). (E) Resorptive inflammatory reaction with histiocytes, multinucleated histiocytic giant cells and lymphocytes, higher magnification of D (HE, obj.-magn, 10×).
