Immunohistochemical analysis of E-FABP expression in oral squamous cell carcinoma and non-tumoral (margin) samples. a Intense positivity of E-FABP in nucleus and cytoplasm of the basal and spinous layer of the normal epithelium, b reaching all epithelial layers. Immunolabeling intensity and proportion varied in tumor samples, with (c) expression in nests of well differentiated areas, d heterogeneous pattern with predominance of low intensity level in tumor cells; and also (e) moderate and (f) high intensity level of staining in nests. Scale bar indicates 50 μm
