Course Objectives: 

Upon completion of this course, students will be able to:

  1. Identify and describe cellular and tissue changes in response to injury
  2. Identify and describe infectious organisms in tissue sections using conventional and special stains
  3. Identify and describe epithelial, mesenchymal, and round cell neoplasms
  4. Identify and describe microscopic lesions in multiple tissues in a wide variety of species
  5. Write and interpret histologic descriptions

Course Description:

The course will be offered online only via zoom or similar in English. Students will have access to digitalized slides for each session, and are expected to analyze the slides before the session (synchronous). At least two faculty members will be connected for each session and will lead the discussion. Topics of discussion will include identification of the organ, disease process, and infectious agents (if present), as well as crafting a morphologic diagnosis for each of the analyzed slides. Students will be asked to volunteer to present cases to the class and contribute to case discussions.


  • Veterinarians/veterinary Surgeons (certificate/copy of diploma required).


  • Access to live sessions, assessment and certificate: $150.00 (FULL)
  • Access to rebroadcast version: $50.00

The following assessments will be included in the course:

DescriptionFormatIndividual worth% overall course grade

The midterm exam will be based on the four cases that are provided based on previously analyzed themes.  Students will be expected to write up each of the cases and include a description, morphologic diagnosis, and comments section.  The final exam will follow the same format and will include four histologic cases.  Discussions about the slides on the midterm and final exams among individuals enrolled in the course are prohibited. 

Course Canvas Site and Notes:

Electronic versions of course materials (notes) will be posted on the course Canvas site a week before the case discussion.  Examples of case write-ups will be posted within 48 hours of the in-class discussion.

Professionalism, Academic Misconduct, Honor Code

All students will be expected to behave in a professional manner, consistent with the Virginia Tech Principles of Community and the guidelines of the Davis Thompson foundation.  Violations will be reported.


At the end of this course, students should have attained the basic capacities to analyze a histologic specimen. This course does not offer a specialist/diplomate status and is not a pre-requisite for a residency program in veterinary anatomic pathology anywhere in the world. This course is intended for veterinarians only. Other disciplines will not be considered.
