I have been having these reddish brown patches on my feet especially my ankles for the last three years and seem to become worse, itchy and sensitive. My dermatologist says that it is Schamberg s disease and has prescribed some Kojic acid cream and an emollient. This did not help much and I was anyway using petroleum jelly to keep these areas moist. I started using fluticasone ointment occasionally which reduced the itching and sensitivity but my patches are still there and a few more have cropped up. I have read about studies with pentoxifylline for this disease and I would like to know, if I can start taking this medication, for how long and any precautions needed and will I be able to get rid of these patches? Thanks . By the way, my father also had this problem and by the time he was in his 70s his entire feet were discolored upto his shins.
