Would you offer radiation to a patient with extensive vulvar dysplasia not amenable to surgical resection and previously resected micro-invasive vulvar cancer in the setting of immunosuppression for solid organ transplant?  

I have never done RT for dysplasia alone in the absence of invasive disease so would avoid it and try other means and keep on close follow up.

Managing vulvar dysplasia in an immunosuppressed patient like this should be approached as the chronic disease that it is. True cure is unlikely, so one will typically rely on temporizing measures, such as surgery, laser, topical agents, etc. I think that the role for radiation therapy is quite limi...

Yes, electron beam or laser.
