A waffle diagnosis is something used to say "I don't know". It is used when a pathologist cannot decide whether something is benign or suspicious for malignant.[1]

Features:

  • Their use should be minimized.
    • Pathologists that use 'em too often aren't doing a good job.
  • They are relatively common in cytopathology.

Examples
