Thrombotic microangiopathy is a group of disorders affecting small blood vessels. Microangiopathic is a disease affecting small blood vessels.[1]
Differential diagnosis
Others:[4]
- Malignant hypertension.[5]
- DIC.
- APLA[6] in SLE.
- Scleroderma renal crisis.
- HIV associated TTP.
- Chemotherapy.
- Calcineurin inhibitor toxicity.
Notes:
- The above cannot be differentiated on a histomorphologic basis.
General
- Underlying pathology: endothelial cell damage.
Microscopic
Features:[7]
- Microvascular occlusion.[8]
- "Loose" intimal thickening; fluffy appearing intima.
- May be have an onion skin-like appearance.
- Fibrin entrapped RBCs.
Notes:
- The last two (#2 and #3) are useful for discrimination from endarteritis.[7]
- Early finding: endothelial cell swelling.
