Lesion
Any kind of structural alteration in cells and tissues
Etiology
cause of the disease
Etiology types
Intrinsic/genetic or acquired
Diagnosis types
Clinical diagnosis Differential diagnosis Clinical pathologic diagnosis Morphological diagnosis Etiological diagnosis Disease diagnosis
Clinical diagnosis
Based on
case history
physical examination
signs
Suggests:
system involved or differential diagnosis
Differential diagnosis
List of possible diseases that could cause the seen lesions or evidence
Clinical pathologic diagnosis
Changes observed in hematology/fluid chemistry based on samples collected from a living patient.
Morphologic diagnosis
Lesion diagnosis
Gross/ histological
Morphologic diagnosis is based on
Predominant lesions in the tissues
What does morphologic diagnosis describe
Lesions:
