A waffle diagnosis, also waffle category, is something used to say "I don't know"; it is a type of equivocation.

In most cases it can be understood/used as a synonym for suspicious for malignancy.

In some classifications, it may be used when the pathologist cannot decide whether something is benign or suspicious for malignant[1] or dysplastic.


Points to remember

  1. These diagnoses essentially say "I don't know"/"I cannot call it benign & I cannot call it malignant".
  2. Their use should be minimized.
    • The use of these diagnoses are often used as quality measures.
      • Pathologists that use 'em too often aren't doing a good job.
      • Good pathologists use 'em when the findings are ambiguous after a diligent work-up.
  3. Generally, they are not considered to have a distinct pathobiology.[2]
