A.Y. 2020/2021
Overall hours
Learning objectives
The course aims to provide students with the knowledge:
i) of the principal diagnostic and instrumental tools of modern pathology to adequately recognize the right clinical context and the right diagnostic procedure in patient management;
ii) of the organization, structure and function of normal cells and tissues and the pathologic principles of cellular/tissue/organ injury, related to the most relevant diseases;
iii) of the specific role of the pathologist in guiding the clinical decisional process in diagnosis, prevention, prognosis and therapy of the single disease;
iv) the ability to correctly interpret a pathology report.
Expected learning outcomes
The student will be able to:
i) choose the right clinical context to ask for a correct pathologic diagnostic procedure during diagnosis, therapy and follow-up of the patient;
ii) use the correct diagnostic pathological algorithm considering their cost-effectiveness ratio;
iii) choose and send the correct surgical specimen to the Pathology Unit;
iv) correctly interpret a pathology report.
Course syllabus and organization

Single session

In the first semester the lectures will take place as concurrent classroms:
·in the classroom with a limited number of students, who have previously booked using the "lezioniUnimi" app with the unimi e-mail account username and password; (…) and at the same time through the "Teams platform" for online students ;
· The student must wear a surgical mask for the entire duration of his/her stay in the classroom and to sit using every other free seat
· the lectures will be recorded and made available on the teacher's Ariel website for students with proven difficulties to connect during classes
· the lectures will take place at the San Paolo Hospital on the 3rd floor of Blocco C. Students must access classrooms via Blocco C and exit via the side blocks (students leaving Pauling and Fleming rooms towards Blocco B and students leaving Curie, Golgi and Pasteur rooms towards Blocco A).
Students must enter from the main hall (R floor) of the San Paolo hospital and undergo body temperature measurement by the infrared cameras. It is strongly recommended to use the stairs for classrooms entering and/or leaving.

Prerequisites for admission
The student must have acquired knowledge of Normal Anatomy and Histology, Human Embriology, Human Physiology, General Pathology and Genetics, to deal with the topics of the course of Pathology.
Teaching methods
The course consists of lectures (2 CFU in the 3rd and 4th years, 5 CFU in 5th), and 6 CFU in the 5th year (lectures: 5 CFU, practical activities: 1 CFU).
Practical activities comprise work in small groups with a following "step by step" debate with the Pathology Professor; clinical cases with necessary histopathological exams (cytological, bioptic and surgical speciments, or autopsies) will be discussed with special focus on the correct use of the algorithm of available pathological procedures and on correct differential diagnosis of patient's disease based on the results obtained; furthermore, the correct comprehention of information in the pathological report will be discussed, too.

Assessment methods and Criteria
Examination consists of an oral test at the end of the fifth years of the course.
No intermediate tests are planned.
Underlined topics of the Course Syllabus are essential to pass the exam.
The student will be asked to:
a) clearly and exhaustively describe the pathological characteristics of the different human diseases.
b) To choose the appropriate clinical context to ask for an histopathological examination during patient's care, therapy and follow up
c) properly use the algorythm of the different available pathological procedures, considering their cost-effectiveness ratio
d) correctly make and send a patient's sample to the pathologist
e) correctly interpret a pathology report
A final score, out of thirty, will be attributed if the exam is passed.
