@linda08 I have either PV or MMP. 3 different dermatologists can't agree on which. Symptoms are essentially the same with different histologies. I have been on Dapsone for 2+ years and can't get any progress for Rituximab infusion. Dermatologists seem more interested in Botox/expensive cosmetics than the more involved tx. I have had only a few skin bullae since beginning the Dapsone. Intraoral lesions and ulcers are the worst. My best treatment for those have been DMSO oral rinses and I use DMSO, castor oil and clobetasol on the the skin areas that want to flare up and it shuts them down pretty quickly. I want to ask MD about subcutaneous IG at next appointment. I can do that myself without the infusion hassle.
