if the spots develop into bigger patches, and the skin surface becomes thinned and crinkled by time then this is probably a disease called Lichen sclerosus. it s not a common one though, The treatment of choice here is an ultrapotent topical corticosteroid (a very strong cortisone cream or ointment). These creams or ointments may be applied daily for several weeks, which will be sufficient to stop the itching. However, long-term but less frequent applications (sometimes as infrequently as twice a week) will be needed to keep the lesions from reactivating and to help restore the skin s normal texture and strength. Treatment does not reverse the scarring that may have already occurred. a good ointment for your case is Tacrolimus. let me know how it s going and feel free to come back for any clarifications. be well :)
