This is quite a difficult case particularly if you had no clinical information. It comes from a patient with known HIV/AIDS. The top right picture is best as it shows the spindled cells permeating between the dermal collagen in addition to the infiltrate.

To me this is very difficult,,There is a deep infiltrate surrounding the fat cells in the first image, with some changes that I am suspecting from this power to be fibrinoid changes in blood vessels????, could the collections of cells that r percieved as endothelial cells be granulomatous collections of histiocytes,,Could it be a granulomatous vasculitis???? Wegner's for example at a certain stage???

I am not quite sure about this one. There are extravasated RBC and a vascular proliferation of epithelioid looking cells with intracytoplasmic lumina, in a sclerotic stroma. I agree that this does look like a sclerotic Kaposi's. I have never heard of this variation but can't think of other differentials. Looking forward to the answer!
