Agree with Igor, the first thing that these images made me think was Kaposi sarcoma. Would perform IHQ to demonstrate HHV8

Very good.  I left out some of the history for this exercise.  The patient is Haitian, black, and HIV positive.  The clinical diagnosis was KS.  I obtained HHV-8, which was positive.  I thought this was plaque stage KS.
