Study Notes

Examination of Specimens

Variety of specimens examined from living patients: tissue biopsies, organs, blood, bone marrow, feces, sputum, and various body fluids (urine, peritoneal, pleural, synovial, cerebrospinal).
Post-mortem examination is conducted during autopsy.

Role of Pathology

Pathology involved in diagnosis, prevention, treatment, and management of diseases.
Requires foundational knowledge of normal and pathologic systems.
Ongoing experience enhances the ability to diagnose and treat patients.

Branches of Pathology

Clinical Pathology

Involves laboratory tests for patient care aimed at diagnosis, prevention, and monitoring diseases.
Conducted by medical laboratory technologists, with pathologists overseeing.

Anatomic Pathology

Studies the impact of disease on the gross and microscopic structures of organs and tissues.

Subspecialties of Anatomic Pathology

Surgical pathology, hematopathology, GYN pathology, cytopathology, transfusion medicine, and autopsy pathology.

Basic Competencies in Pathology

Core principles include disease mechanisms such as:
- Cell injury, death, and adaptations.
- Inflammation and repair processes.
- Hemodynamic disorders, immune system diseases, neoplasia, genetics, pediatric diseases, and environmental/nutritional diseases.

Inflammation

Acute inflammation is immediate, involving vascular changes and neutrophils.
Chronic inflammation features prolonged response, involving lymphocytes, macrophages, and tissue repair.

Repair Mechanisms

Initiated with inflammation, including hemostasis and the regeneration of cells.
Angiogenesis (new blood vessel formation) and fibrosis (scarring) are key elements.

Diagnostic Techniques

H&E stained tissue sections are evaluated for diagnoses, differentiating between neoplasms, infections, or inflammation.
If neoplasm is suspected, ancillary techniques like immunohistochemistry and molecular/genetic studies are utilized to ascertain subtype and origin.

Cytopathology

Involves examining cells from different body sites to elucidate disease causes.

Intraoperative Consultation

Frozen section diagnostics guide surgical decisions regarding lesion nature, tissue adequacy, and surgical margins.

Clinical Case Example

62-year-old man with a history of smoking and melanoma presented with a lung nodule.
Differential diagnosis includes malignancy (metastatic melanoma or lung adenocarcinoma) vs. inflammation.

Learning Objectives

Understanding pathology's role in disease management.
Describe mechanisms of disease.
