In order to evaluate the potential different fraction of dysplastic/neoplastic cells in the samples analyzed, the percentage of the biopsy involved by the lesion was evaluated in all cases. The morphometric evaluation was performed by scanning all H&E stained slides with a whole slide scanner Ventana iScan HT (Roche Diagnostics, Sant Cugat, Spain) at a magnification of 20×. The high-resolution digital images of the tissue sections were measured using the Virtuoso viewer (Roche, Sant Cugat, Spain), which includes measuring tools. The total area of the biopsy, the total area occupied by squamous epithelium, and the area involved by the dysplastic epithelium were measured in each biopsy.

All the cases were digitized in a VENTANA iScan HT (Roche-Ventana Medical Systems, Tucson, AZ, USA) at a magnification of ×20. The system creates high-resolution digital images of tissue sections. All files were stored on a server hosted at the Spanish Division of Roche Diagnostics. The students access the virtual slides through a hyperlink on the Moodle platform, using their own computers as virtual microscopes. The images are viewed in the Virtuoso viewer (Roche-Ventana Medical Systems, Tucson, AZ, USA), which works as a web browser and simulates a CM [Figure 1]. Virtuoso is designed to organize the images into different cases and the cases into groups. No specific software installation is required to visualize the virtual slides.
Two supporting pdf files were posted on the main page of the discipline in the Moodle platform. One included general information to guide student accession to the viewer and the username and password necessary to accede to the website. The second pdf file included educational text discussions for each particular case.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
