Representative examples of immunostaining of CD66b + neutrophils (in red) or CD8+ lymphocytes (in black) from intratumoral (A, B, C, D) or peritumoral (E, F, G, H) areas of esophageal squamous cell carcinoma (x400). A, E infiltrated mainly by CD66b + neutrophils (black arrow); B, F infiltrated mainly by CD8+ lymphocytes (white arrow); C, G infiltrated by both CD66b + neutrophils and CD8+ lymphocytes; D, H infiltrated by low density of the inflammatory cells.
