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, epithelioid sarcoma
IHC CD31 +ve, CD34 +ve, factor VIII +ve, CAMTA1 +ve, TFE3 +ve/-ve
Molecular gene fusions: WWTR1-CAMTA1 (approximately 90% of cases), YAP1-TFE3 (small number of cases)
Site soft tissue - see vascular tumours, classically liver - but various sites reported
Prevalence rare
Prognosis moderate
Treatment resection

Epithelioid hemangioendothelioma, abbreviated EHE, is rare malignant vascular tumour.

It should not be confused with epithelioid hemangioma.

General

Treatment:

Prognosis - liver:

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.

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.
