I encountered one of these on my unit, which is a cardiac floor, but this patient was admitted for sepsis and anemia. Patient had breast cancer. The right arm up to the right side of the neck looked like cellulitis but the right chest/breast area and wrapping around to the back was a very nasty wound. Seeping, draining, bleeding. It was so painful for the patient and I felt so bad for her. Dressing changes took a long time.
The gold dust is definitely interesting, I have never heard of that before!
