Pathology Puzzles Project gives an opportunity to all the specialists to study interesting morphological cases. It is not only a good educational opportunity but also a chance to discuss the cases within the pathologists’ community. Every month three cases will be uploaded into the Digital Pathology system. Before uploading the cases minimum two specialists will validate them.
