Veterinary Pathologist Course

Lesson 1 • Cellular Injury and Adaptation

Covers mechanisms of cell injury, death, and adaptive responses. Provides the mechanistic basis for interpreting lesions in later chapters.

Lesson 2 • Core Pathology Terminology

Introduces standardized nomenclature for lesions, processes, and diagnoses. Precise language underpins accurate reporting throughout the course.

Lesson 3 • Inflammation Fundamentals

Explains acute and chronic inflammation, cellular mediators, and tissue outcomes. Inflammatory patterns recur across organ systems studied later.

Lesson 4 • Introduction to Necropsy Procedure

Outlines systematic necropsy workflow, safety protocols, and documentation standards. Establishes procedural discipline required for all practical sessions.

Lesson 1 • Systematic Gross Examination Techniques

Teaches organ-by-organ examination methods and lesion characterization criteria. Systematic technique reduces missed findings during necropsy.

Lesson 2 • Gastrointestinal and Hepatic Gross Lesions

Covers gross changes in the digestive tract, liver, and pancreas. Organ-specific patterns guide tissue sampling decisions.

Lesson 3 • Musculoskeletal and Nervous System Lesions

Addresses gross findings in muscle, bone, joints, brain, and spinal cord. Neurologic and locomotor lesions require specialized examination steps.

Lesson 4 • Cardiovascular and Respiratory Gross Lesions

Identifies common gross changes in heart, vessels, lungs, and pleura. Connects vascular pathology to systemic disease patterns.

Lesson 1 • Immunohistochemistry Principles

Explains antigen retrieval, antibody selection, and chromogen detection for tissue-based immunolabeling. IHC extends morphologic diagnosis to molecular characterization.

Lesson 2 • Microscopic Lesion Interpretation

Develops systematic microscopic examination skills and lesion characterization at cellular level. Microscopic findings refine gross diagnoses established earlier.

Lesson 3 • Tissue Fixation and Processing

Covers fixative selection, fixation ratios, and automated tissue processing steps. Proper fixation is prerequisite to all histologic interpretation.

Lesson 4 • Routine and Special Staining Methods

Teaches hematoxylin and eosin staining and targeted special stains for specific tissue components. Stain selection directly affects diagnostic accuracy.

Lesson 1 • Coagulation and Hemostasis Testing

Addresses prothrombin time, activated partial thromboplastin time, and fibrinogen assays. Coagulation data supports diagnosis of hemorrhagic and thrombotic lesions.

Lesson 2 • Urinalysis and Renal Assessment

Explains urine sediment examination, dipstick interpretation, and urine protein-to-creatinine ratios. Urinalysis findings complement renal histopathology.

Lesson 3 • Cytology Techniques and Interpretation

Covers sample collection methods, smear preparation, and cytologic diagnosis of masses and effusions. Cytology provides rapid pre-histologic diagnostic information.

Lesson 4 • Serum Biochemistry Panels

Teaches organ-specific enzyme and metabolite interpretation for liver, kidney, and muscle. Biochemical patterns guide tissue sampling and differential prioritization.

Lesson 1 • Bacterial and Mycoplasmal Pathology

Covers suppurative, fibrinous, and necrotizing lesions caused by bacterial pathogens. Bacterial morphology in tissue guides culture and molecular confirmation.

Lesson 2 • Fungal and Algal Pathology

Identifies tissue morphology of systemic and opportunistic fungi and algae. Fungal stains and morphologic features distinguish genera in tissue sections.

Lesson 3 • Parasitic Pathology

Describes tissue reactions to protozoa, helminths, and arthropod parasites. Parasite identification in tissue sections supports definitive etiologic diagnosis.

Lesson 4 • Ancillary Infectious Disease Diagnostics

Integrates PCR, in situ hybridization, electron microscopy, and culture with morphologic findings. Ancillary tests confirm etiologic diagnoses beyond morphology alone.

Lesson 1 • Comparative and Spontaneous Tumor Models

Examines naturally occurring animal tumors as models for human oncology research. Comparative pathology expands the pathologist's role in translational science.

Lesson 2 • Principles of Neoplasia

Establishes criteria distinguishing benign from malignant neoplasms and tumor nomenclature. Oncologic terminology and criteria underpin all tumor classification work.

Lesson 3 • Tumor Staging and Margin Evaluation

Teaches TNM staging principles, surgical margin assessment, and lymph node evaluation. Staging data directly informs clinical management decisions.

Lesson 4 • Round Cell and Hematopoietic Tumors

Addresses lymphoma, mast cell tumor, histiocytic sarcoma, and plasma cell tumors. Round cell tumors require IHC and cytology for definitive classification.

Lesson 1 • Mycotoxin and Plant Toxin Pathology

Identifies lesions from aflatoxins, trichothecenes, pyrrolizidine alkaloids, and other plant toxins. Feed and forage history is essential context for these diagnoses.

Lesson 2 • Principles of Toxicologic Pathology

Covers dose-response relationships, target organ concepts, and toxicokinetics relevant to lesion interpretation. These principles frame all subsequent toxicologic case analysis.

Lesson 3 • Nutritional Deficiency and Excess Pathology

Covers lesions from deficiencies in vitamins, minerals, and essential nutrients and from hypervitaminosis. Nutritional pathology is common in production animal cases.

Lesson 4 • Hepatotoxic and Nephrotoxic Lesions

Identifies zonal hepatic necrosis, cholestasis, and tubular nephropathy caused by specific toxin classes. Organ-specific patterns narrow the list of causative agents.

Lesson 1 • Diagnostic Report Composition

Develops complete necropsy and biopsy report writing with gross, microscopic, and interpretive sections. Report quality directly affects clinical and regulatory utility.

Lesson 2 • Case Presentation and Peer Discussion

Builds skills for presenting cases in conference settings and responding to peer critique. Oral case presentation is a core professional competency for pathologists.

Lesson 3 • Multi-System Disease Case Analysis

Applies integrated diagnostic skills to cases involving multiple organ systems simultaneously. Multi-system analysis reflects real-world complexity of field submissions.

Lesson 4 • Quality Assurance in Diagnostic Pathology

Covers proficiency testing, second-opinion protocols, and laboratory accreditation requirements. Quality systems ensure diagnostic reliability and professional accountability.
