Hyperkalemia is a critical value as it is associated with cardiac arrhythmias.
Critical values is a concept which comes to anatomical pathology from clinical pathology.[1]
In the context of surgical pathology, it is, perhaps more appropriately, called critical diagnosis.
The general consensus is that these findings (critical valves, critical diagnoses) require a phone call and/or discussion with the clinician to ensure the situation is managed appropriately in a timely manner.[2]
List of critical diagnoses
Cytology
Critical diagnoses as per Pereira et al.:[2]
- Unexpected malignancy - vast majority of cases.
- Microorganisms in non-gynecologic specimens and FNA specimens.
Surgical pathology
The following is primarily constructed from a list in Pereira et al.[3]
General
- Large vessel in core biopsy specimen.
- Unexpected malignant diagnosis.
- Malignant diagnosis in the context of a medical emergency:
- Neoplasm causing paralysis.
- Malignancy causing superior vena cava syndrome.
Gynecologic
- D&C on pregnant individual (or specimen labelled "products of conception") without chorionic villi or trophoblasts.
- Fat on endometrial biopsy.
- Fat on endocervical canal sampling.
Diagnostic of infection
- Fungal.
- Microbacterial.
- Bacterial.
- Viral.
Suggestive of infection
- Necrotic granulomas.
Cardiac
- Mesothelial cells in heart muscle biopsy.
- Transplant rejection.
Medical diseases
Renal
- Crescents in kidney biopsy.
List of diagnoses that should be reviewed
- AKA review diagnoses.
Review diagnoses are diagnoses that have significant treatment implications, and often mandate the opinion of a second pathologist and/or a sub-specialist. There is no general consensus around which diagnoses require review.
Examples of diagnoses that are high impact and are frequently reviewed:
- High grade columnar esophageal dysplasia.[4]
- Muscle invasive urothelial carcinoma of the bladder.[5]
