Does anybody know what a biopsy for lupus would show? I had a sun spot biopsied and the GP noted I had a possible autoimmune rash ( I have a malar rash) and the pathologist said I had chronic inflammatory cells around the subepithelial connective tissue. I have had high ESR and CRP, low iron, elevated liver enzymes etc and have responded to prednisone but need an official diagnosis. What would rosacea histopathology show up as? I'm heading towards another biopsy but if the one I had done for the sun spot is sufficient I won't.
