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
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:[7]
- Angiosarcoma, epithelioid.
- Hemangioma.
- Cholangiocarcinoma.
- Fibrolamellar hepatocellular carcinoma.
