Epithelioid hemangioendothelioma
Diagnosis in short

Epithelioid hemangioendothelioma. H&E stain.

LM large epithelioid perivascular cells with abundant pale eosinophilic cytoplasm and cytoplasmic vacuolation ("blister cells") - may form lumen and have RBC within, vesicular nucleus +/-prominent nucleolus; tuft-like projections into capillaries; cells may be in well-circumscribed paucicellular nodules or poorly formed cellular aggregates
LM DDx epithelioid angiosarcoma, hemangioma

Prevalence rare
Prognosis moderate
Treatment resection

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]

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.
