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.
- Outline the core competencies in pathology.
- Discuss diagnostic approaches for neoplasms, emphasizing molecular testing and tumor markers.
Opportunities in Pathology
- Shadowing opportunities and post-sophomore pathology fellowship available. Contact for details.
