The prognosis significance and application value of peritoneal elastic lamina invasion in colon cancer - Fig 1
A:Tumor cells approached the serosa, as shown by the red arrow (H&E, 200 x) .B: The deepest tumor cells approached PEL but did not exceed PEL highlighted with an elastic stain. As shown by the red arrow (Elastic fiber staining, 200 x) . C: Tumor cells invaded the serosa, accompanied by significant inflammatory response, fibrous tissue and angiogenesis hyperplasia. as shown by the red arrow (H&E, 100 x) .D: Invasion through PEL highlighted with an elastic stain, as shown by the red arrow (Elastic fiber staining, 100 x) . E: Tumor cells appeared on the serosal surface, accompanied by inflammatory responses and erosion, as shown by the red arrow (H&E, 100 x) . F: Invasion through PEL highlighted with an elastic stain, as shown by the red arrow (Elastic fiber staining, 100 x).
