Figure 3 from Two Molecular Subgroups Predict Most Recurrences in Advanced Laryngeal Squamous Cell Carcinoma

Representative hematoxylin and eosin and IHC staining from two cases. Case 3: (A1.1) hematoxylin and eosin of tumor surface, (A1.2) VEGF-A IHC at tumor surface, (A2.1) hematoxylin and eosin of tumor depth, and (A2.2) VEGF-A IHC at tumor depth, showing no qualitative differences between regions. Case 5: (B1.1) hematoxylin and eosin of tumor surface, (B1.2) VEGF-A IHC at tumor surface, (B2.1) hematoxylin and eosin of tumor depth, and (B2.2) VEGF-A IHC at tumor depth, with a slight tendency toward stronger expression in the depth.
