Greetings. I am a retired periodontist and also have pemphigus vulgaris although I am arguing with my dermatologist who thinks it is bullous pemphigoid. Minor difference in proteins that are attacked. My biopsy was a skin bulla that popped up the morning of my appointment with her. The oral problems are far more prevalent and painful. Currently taking Dapsone which works OK and has minimal side effects. Have been asking about Rituximab but my docs seem a bit wary of the infusion treatments. And, yes, your diet will look nothing like what you were used to. I eat a lot of yogurt nowadays.
