I also thought first in epithelioid angiosarcoma. IHC is needed.

DDx: In rough order - Carcinoma (probably metastatic, epithelioid, rhabdoid, hepatoid & focally syncytial - consider hepatocellular carcinoma given site and age), less likely melanoma, sarcoma, germ cell (embryonal carcinoma/MTU) etc. Just also thought of mesothelioma - should not forget it.

Forgot to say I just posted Friday's "opinion" - I seem to be in the minority!

I would like to thank everyone for your comments. The final diagnosis can not be rendered without Immuno' and based on this and the morphology the diagnosis is Proximal type Epithelioid Sarcoma. The most helpful image is the low power - the 'proximal type' ES's show more pleomorphism and necrosis and are more aggressive than their distal counterparts.
