I have had a rash for four months now. i have done prednisone (sp?) and corticosteriods on and off ( 2 weeks on 2 weeks off) it seems like every time I go off the steroids the rasChatDoctore back - I have had a CBC which revaled elevated platelets - white count was within normal range. I also had a biopsy to rule out mycosis fungoides . Should I be concern that this seems to come right back or that my platelets are high?
Hi there. 4 months is a long time to have any particular rash.  Dermatology is a very visual field & as such, this rash needs to be viewed & it would be great if you could upload a clear digital photograph of the lesion onto this website using the upload data icon. Alternatively, do visit a second dermatologist for best results as you seem to have done a skin biopsy as well. What were the results of the biopsy?  One should test for allergens but that is only possible 2 weeks after complete stoppage of the corticosteroids. Elevated platelets need not be significant, but a host of other tests are required & you need to be seen in person am afraid. Cheers & wish you a speedy recovery.  Chat Doctor.
