Learning objectives
This course will be mainly focused on the morphologic and molecular techniques applied to the study of pathologic cells and tissues, crucial to provide the pathologist with the best-quality cyto-histologic samples, equipped with all the additional informations necessary to reach the most accurate diagnosis.
This course will lead the students to develop knowledge and understanding of the basic principles for the correct handling and processing of histologic and cytologic samples. Moreover, thorough knowledge and understanding of the basis of the morphologic, histochemical and immunohistochemical techniques ancillary to pathologic diagnosis will be reached. Training periods in the histopathology laboratories will allow the students to practically apply the acquired theoretical knowledge.
The students will also acquire:
- knowledge of the specific measures for safety and prevention, that will make them able to work in the Pathologic Anatomy laboratories in a mindful way, without causing damage to themselves, to collegues and to the environment;
- the ability to analize in a critical way all the phases of the technical work, reaching a judgement-making capacity that will allow them to contribute to identify and solve possible technical troubles in the laboratory procedures;
- communication skills that will be of paramount importance to estabilish cooperation with collegues and with biologist and pathologists, in order to discuss technical results and propose critical evaluation of the procedures falling within their competence. This will help to improve the quality of the technical work carried out in the pathology laboratory, eventually contributing to improve the final product, i.e. the cyto-histopathologic diagnosis;
- learning skills that will allow them to self-sufficiently follow the evolution of the technological and instrumental progress in the pathology field, in order to understand and, in case, contribute to the introduction of new technical advances.
Prerequisites
Knowledge of the basis of histology and having passed all the first year's exams.
Course unit content
The first lessons of the course will be focused on the procedures that characterize a Histopathology laboratory, including its organization, software management system, instrumentation and specific measures for safety and damage prevention. All the technical steps undertaken by a histologic sample since its acceptance at the institute of Pathologic Anatomy will be fully explored: they include fixation, processing, paraffin embedding and sectioning of histologic slides. Similarly, the pathway followed by cytologic samples will be taught. Also the rationale and the technical procedures for intraoperative histologic examination by means of frozen section, a rapid test that can influence the course of a surgical operation, will be covered.
The second part of the course will be dedicated to the cyto-histologic stains essential to the identification of cell/tissue components, structures and specific chemical substances, in normal and pathologic conditions. Both the classic histomorphologic/histochemical stains (hematoxylin-eosin, PAS, etc) and the more recent immunohistochemical procedures will be fully covered. Such stains represent a valuable aid to the pathologist to reach the most accurate diagnosis.

Teaching methods
The course will be based on frontal teaching: attendance to at least 70% of the classes will be mandatory. Lectures will be held on-site in compliance with safety standards, provided that further instructions on the ongoing health emergency are not implemented.
Assessment methods and criteria
Achievement of learning outcomes will be verified by means of a final oral exam, whose score will be expressed in thirtieth; the minimal threshold to pass the exam will be 18/30, the best mark will be represented by 30/30 “cum laude”. By means of a series of questions touching a wide variety of topics treated during the course, the global level of knowledge and understanding of the theoretical and practical subjects, as well as the ability to logically think and connect related topics, will be verified.
