Histopathological images of oral squamous cell carcinoma and normal tissue

Serial sections of 4–5 μm retrieved from the tissue blocks of cases of OSCC and normal tissue stained with hematoxylin and eosin (H and E) stain. The tissue blocks were obtained from the archive of Oral Pathology Department, Faculty of Dentistry, Alexandria University, Egypt. A total number of 115 cases, 49 cases of OSCC with different grades (low, intermediate and high) as a study group, and 66 cases with normal histology as a control group were included in the dataset. Histological images were captured by Olympus Microscope DP20 Camera attached to Olympus BX41- P Polarizing Light Microscope, California, USA using CellSens standard software. Two sets of images were captured. The first set was captured with 40x objective lens with a total magnification of 400x to take a total number of 427 images of OSCC and 437 images of normal tissue. The second set was captured with 10x objective lens with a total magnification of 100x to take a total number of 421 images of OSCC and 429 images of normal tissue. All images were saved as JPEG format in the size of 1,600 × 1,200 pixels.
