Diagnosis a concise statement or conclusion
concerning the nature, cause, or name of a disease.
(note: the accuracy of a diagnosis is limited by the evidence available for
study)

Differential Diagnosis (“rule-outs”)
• A list of diagnoses that could account for the history, clinical signs or lesions in a case.

Clinical Diagnosis
• Diagnosis based on data obtained from the case history, clinical signs, and physical examination.

Morphologic Diagnosis (lesion diagnosis)
• A diagnosis based on the predominant lesion(s) in the tissue.
• it may be macroscopic (gross) or microscopic (histologic) and describes the severity, duration,
• distribution, location and nature (eg degenerative, inflammatory, neoplastic) of the lesion.
• eg. severe, acute, locally-extensive, fibrinous bronchopneumonia.

Etiologic Diagnosis
• a definitive diagnosis that names the specific cause of the disease.

Disease (Definitive) Diagnosis
• a specific diagnosis that states the “name of the disease”.

Anatomic Terminology
• ORGAN + OPATHY (disease of an organ; the etiology / pathogenesis is not entirely clear).
• Hepatopathy - any disease of the liver.• Nephropathy - any disease of the kidney.

Anatomic Terminology
• ORGAN + OSIS (noninflammatory disease of an organ, often used if degeneration / necrosis)
• e.g. Hepatosis - esp. when degeneration &/or necrosis of hepatocytes.
• Nephrosis - esp. when degeneration &/or necrosis of tubules.

Anatomic Terminology
• ORGAN + ITIS (an inflammatory disease of the organ).
• Hepatitis - inflammation of the liver.• Nephritis - inflammation of the kidney.• Lung + itis = ?
