thanks for your patience.
I can understand your concern.
I reviewed the pictures, there are two possible diagnosis:-
2. Lichen sclerosus et atrophicus
These are the two possibilities.
vitiligo is a progressive disorder and would take time to resolve . It is discolouration of the skin. it can spread anywhere on the body.
Lichen sclerosus et atrophicus is a chronic inflammatory condition which presents as leucoderma and also acute and chronic balanoposthitis and scarring that can result in significant sexual and urinary dysfunction.
It is important to know what it really is, since you have associated phimosis, so lichen sclerosus et atrophicus, seems more likely. It would be advisable to go in for a biopsy to know the exact diagnosis.
I would advise you to continue the steroid cream till the exact diagnosis is known.
Elidel cream will be useful in both the conditions. it will require a prescription.
Please let me know if you have any queries.
Hope my recommendations are helpful.
