These look like vascular channels lined by atypical hobnailed endothelial cells. A couple of the channels contain red blood cells. I think this is probably a malignant vascular tumor, but I guess I couldn't totally rule out something benign, like a hobnail hemangioma based on this picture alone. It being in the skin, Kaposi sarcoma is a consideration, though to me, it doesn't have the typical histological pattern and is a little too atypical. Angiosarcoma is on the list. I would get CD31 CD34 Factor VIII and prove it was vascular, and maybe an HHV8 if there was reason to believe he may have Kaposi.

Agreed - I fall on the malignant vascular side. Unfortunately, this picture was donated by a colleague and I don't have immunostains.
