Angiosarcoma is an uncommon malignant vascular tumour.
General
- Malignant tumour - general has a poor prognosis.[1]
Epidemiology:
- May arise secondary to chronic lymphedema related to breast carcinoma.
- Known as Stewart–Treves syndrome.[2]
- Association with radiation - breast,[3] urinary bladder.[4]
- Liver angiosarcomas are associated with vinyl chloride exposure.[5]
- Cutaneous angiosarcomas are classically seen on the head and neck of whites over 60 years old.[6]
Gross
- Red/dark tan lesion.
- Typically poorly circumscribed.

Microscopic
Features:
- Spindle cell lesion.
- Occasionally an epithelioid lesion.
- Very many small capillaries of irregular shape lined with:
- Pleomorphic nuclei - important.
- May have hobnail morphology.
- Usually "red" at low power - due to many RBCs - important.
- Pleomorphic nuclei - important.
- Mitoses.
- Cytoplasmic vacuoles.
- Cells trying to form lumina - embryologic.
Notes:
- Epithelioid variant (with abundant cytoplasm & sheeting architecture) may resemble melanoma or a carcinoma (such as hepatocellular carcinoma or urothelial carcinoma[7]).
DDx:
- Atypical vascular lesion.
- Kaposi sarcoma.
- Anastomosing hemangioma - especiallly in the kidney.
- Poorly differentiated carcinoma, e.g. urothelial carcinoma.
- Other vascular tumours.
