Elastic lamina staining of patient tissue sections. A, B The elastic lamina showed a “ring pattern”, and tumor cells invaded the elastic lamina, evaluated as pT3 ELI (+). S: serosal; T: tumor. The black arrow indicates the elastic lamina; (A: × 40, B: × 100). C, D The tumor approached the serosa but did not penetrate the elastic lamina, evaluated as pT3 ELI (−); S: serosal; T: tumor. The black arrow indicates the elastic lamina; (C: × 40, D: × 100). E, F The tumor approached the serosa but showed no staining for the elastic lamina, evaluated as pT3 EI (−); S: serosal; T: tumor. The black arrow indicates the elastic lamina; (E: ×40, F: × 100)
