The medical community has a lot of unanswered questions about this skin condition including what the heck causes it. The etiology is unknown... It might be a reaction to a viral infection or it may be caused by something else completely. Here's what they do know. The condition begins with a red scaly patch, which gets to be about 1-2 inches in diameter. Its called a herald patch. Mine was on the top of my arm near my elbow. A few days later, all hell breaks loose and red patches - lots of them - develop over a short period of time. They occur mostly on the trunk of the body and down the legs. For some folks they itch like crazy but mine have been pretty quiet. There is no known cure. Steroids may help the itch but won't make the patches resolve. Antibiotics and anti-fungals don't help because it isn't bacterial or fungal in nature. The only cure comes with time. It can take anywhere from a few weeks to a few months for it to disappear and it may or may not reoccur. Ok, I can deal with this.
My theory is that the rituxan treatments are suppressing my immune system making me susceptible to weird crap such as pityriasis rosea.
