VAIL, COLO. -- Asking whether a vulvar skin lesion itches or burns provides an early indication of how easy treatment is likely to be, Dr. Barbara R. Reed said at a conference on obstetrics and gynecology sponsored by the University of Colorado.
An itchy lesion that feels really good to scratch is probably going to respond easily to treatment.
Patients who report this sort of symptom typically have a skin disorder
featuring thickened skin, which releases a chemical that causes itching. This thickened skin stands up well to the rigors of treatment, explained Dr. Reed, a dermatologist at the university.
An example would be lichen simplex chronicus. Upon physical examination, this disorder is marked by lichenification, perhaps fissuring, and thickened skin. "Biopsy the involved skin to get the diagnosis. You are home free when you diagnose lichen simplex chronicus, because it's easy to treat," she said.
Treatment consists of using a potent topical steroid such as clobetasol for a couple of weeks, tapering down over the course of several more weeks to progressively lower-potency steroids.
"If they're really itchy at night, start with 10 mg of hydroxyzine. I don't care what the size of the person is--people really differ in their response to oral antihistamines. If you start with 25 mg and they can't get up the next morning, they're never going to take another pill with that name on it," Dr. Reed said.
