Fig. 4From: Curative resection after chemotherapy and chemoradiotherapy for postoperative recurrence of pancreatic tail cancer in the abdominal wall: a case reportGross and histopathological findings of the primary pancreatic cancer and abdominal wall recurrence. a The cut surface of the original resected specimen was 3.3 × 2.8 × 2.0 cm in size. The tumor was whitish and had invaded the splenic vessels (white arrows). b Microscopic findings (hematoxylin and eosin [HE] staining × 100) showed proliferation of the tumor cells, which were composed of large, atypical tubules, indicating a well-differentiated adenocarcinoma. c The cut surface of the resected first recurrent specimen was 6.0 × 4.8 × 4.5 cm in size. There were no tumor cells on the surgical margin, but it was close to the colonic mucosa (yellow arrows) and the transected plane (white arrowheads). d Microscopic findings (HE staining × 100) showed atypical ductal cells resembling primary pancreatic ductal adenocarcinomaBack to article page
