A waffle diagnosis, also waffle category, 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]
Points to remember
- These diagnoses essentially say "I don't know"/"I cannot call it benign & I cannot call it suspicious".
- 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.
- The use of these diagnoses are often used as quality measures.
- Generally, they are not considered to have a distinct pathobiology.[2]
Examples
Cytopathology
- Atypical squamous cells of unknown significance (ASCUS) - gynecologic cytopathology.
- Atypical glandular cells of unknown signficance (AGUS) - gynecologic cytopathology.
- Follicular lesion of unknown significance (FLUS) - thyroid cytopathology.
