PM reports

• To describe any lesion, use the following criteria:

  1. Location
  2. Number/extent
  3. Demarcation
  4. Distribution: Focal, multifocal, focally extensive, multifocal to coalescing, diffuse, random, segmental....
  5. Color
  6. Size (metric units)
  7. Shape
  8. Consistency and texture
  9. Any particular smells or sounds should also be recorded.
• a morphological diagnosis is based on what is seen, so the predominant lesions in the tissues macroscopically
• a morphological diagnosis describes severity, duration, distribution, location (organ or tissue), and the disease process (degenerative, inflammatory, neoplastic) of the lesion

  • Duration: peracute, acute, subacute, chronic
  • Severity: Mild, moderate, severe
  • Distribution: Focal, multifocal, focally extensive, multifocal to coalescing, diffuse
• Neoplasia has a different layout for morphological diagnoses (Organ: Neoplasia) because modifiers are irrelevant (ex. There is no “mild”  lymphoma)
• morphologic diagnosis = macroscopic diagnosis
