Topic Introduction to Pathology
And Forensic Medicine

By S. Pongsabutra MD.
  • Contents of Learning

  • 1.The meaning and scope of pathology.
  • 2. How to learn the Pathology.
  • 3.The main cluster of diseases.(roots of
    diseases)
  • 4. Application Pathology for the clinical work
    or other objectives such a tool of research work
    and public health care.

8
1. What is Pathology
  • Pathology is study the abnormal state of body
    particularly in morphology (structure) and
    function (physiology) of organ, tissue, and cell.
    Which have been changed from the normal by the
    influences of environments.
  • Or
  • Pathology is the medical science specialty
    practice concerned with all aspects of diseases

What is the disease
  • Disease (disease) is the disordered of body
    function, (organ systems) resulting suffering,
    torture of the body which show off by symptoms
    signs of affected parts complained by that victim.

Systemic Pathology
(??????????????????????????????????????????????
???????)
  • Disease of Organ system consisting
    of

    1 Cardiovascular system (CVS eg, heart, blood
    vessel.)
    2. Respiratory
    system ( RS )
    3. Gastrointestinal system include
    liver,biliary tract and pancrease (GI )
    4. Kidney Urinary Bladder (KUB)
    etc

13
METHOD OF LEARNING
B. Practical study there
are 2 ways
A. THEORETICAL STUDY
Indirect study (study the Pathological changes in
life by Application the scientific tools and
laboratories to find out the lesions.)
Direct study (take out the affected cells
,tissues, organs from either the life or body for
direct examination the pathological changes in
the laboratory.)
14
A. THEORETICAL STUDY
There are 6 main objects to study the DISEASES
-
1. Etiology
2.
Pathogenesis (the process or changing mechanism)
3. Pathological changes (structural
changeslesion) 4. Clinical feature (symptoms
and signs of patient due to structure
functional changes)5. Complication secondary
changes (both of structure and function) of the
other related organs ( ????????????????
????????????????????? )
6. Prognosis Prediction
the disease outcome on patient in the future

Descriptive term Gross Pathology of Liver
Liver show focals loss of parenchymal tissues
(technical term is liquefaction necrosis)
20
Descriptive term gross Pathology of Liver
Abnormal surface of liver shows diffuse small
nodular lesions size1-2 mm with shrinkageof
contour
21
Severe, Diffuse dilatation of sinusoid with
reddish brown color cut surface
22
Abnormal cut surface characterized
by multiple,nodules varying in
size, up to 1 cm. grey white color (neoplasia)
23
Liver
Abnormal cut surface show diffuse small white
solid masses size vary from 1-3 mm.
24
Descriptive term Histopathology
Opisthorchis in Hepatic bile duct

25
Abnormal Changes characterized by necrosis of
Liver cells cords around Central vein
26
Abnormal both in size, shape of liver Cells
with marked disorders arrangement (or loss of
normal) of architecture

Mitral Valve stenosis
Diastolic Murmur gr.4
Leaflets characterized by stiffness, fused
together ,narrow opening and shortening of
chordae tendinae
Difficulty of blood flow pass through Mitral
Valve stenosis during Lt. Atrium Systole and
Lt. Ventricle- Diastole create abnormal sound
called murmur
