Dermal lymphocytic infiltrate and extravasation of RBCs and an orange colour clinically seen suggest lichen aureus. The clue that the patient is on multiple drugs also suggests a drug-induced pigmentary purpura.

A patched lesion of KS could simulate a purpuric dermatitis...couldn’t it?  I know the back isn’t an usual site, but would like to see a HHV8 stain.

Perfect. You guys thought of all the correct possibilities. 

Lichen aureus. HHV8 is negative. The drug induced PPE is also a good thought; the clinician thought this was classic for lichen aureus, just in an HIV+ individual.
