Galectin-3 expression determined by immunoperoxidase staining. (A) Positive control. (B) Negative control (non-Hodgkin's lymphoma). (C) Normal larynx negative for galectin-3. (D) Low expression of galectin-3 in in situ laryngeal carcinoma, with a few immunolabeled cells and weak staining intensity (arrows). (E) High expression of galectin-3 in invasive laryngeal carcinoma without metastases, showing diffuse and high-intensity immunolabeling. Bar = 100 μm.
