Epithelioid hemangioendothelioma, abbreviated EHE, is rare malignant vascular tumour.
It should not be confused with epithelioid hemangioma.
General
- Malignant.[1]
- Adults - wide age range.
- Associated with oral contraceptives, vinyl chloride.[2]
- Rare.[3]
Treatment:
- Excision[4] if feasible.
- Chemotherapy - not standardized.[3]
- Liver transplantation.[5]
Prognosis - liver:
- ~55% five-year survival.[4]
- Better than other liver tumours.
Gross
- Classically, a liver lesion - but found elsewhere.[6][7]
- Case reports of EHE in a wide number of anatomical sites (bowel,[8], parotid[9] mediastinum[10]).
Microscopic
Features:[2]
- Large epithelioid perivascular cells with:
- Abundant pale eosinophilic cytoplasm.
- Cytoplasmic vacuolation (some cells) - AKA "blister cells" - key feature.
- May form lumen and have RBC within.
- Vesicular nucleus with prominent nucleolus in some cells.
- Tuft-like projections into capillaries.
- Tumour cells may be in well-circumscribed paucicellular nodules or more cellular poorly formed aggregates.
DDx:[11]
- Angiosarcoma, epithelioid.
- Hemangioma.
- Cholangiocarcinoma.
- Fibrolamellar hepatocellular carcinoma.
- Epithelioid sarcoma.[12]

IHC
Features:[2]
- CD31 +ve.
- CD34 +ve.
- Factor VIII +ve.
- CAMTA1 +ve.[12]
- TFE3 +ve - minority of cases.
Molecular
Gene fusions:[12]
- WWTR1-CAMTA1 - seen in approximately 90% of cases.
- YAP1-TFE3 fusion gene - <5% of cases.
