Dear Sir, I m from Bangladesh. I used to smoke. But I ve left smoking since 1.5 years. I have 2 white patches on my tongue and inside cheek since last 2 years which are not harden and also not raised. One dentist told me that it is lichen planus and another dentist told me that it is Leukoplakia . I did biopsy 16 months ago which said squamous hyperplastic chronic inflamatory cell found but no malignancy was found. I took konalog in orabse (Triamcinolone Acetonide), Vitamin A (5X50000 = total 250000 IU), Flukonazole. After taking this white patch inside my cheek went out for 2 months. After 2 months it appears again. I ve changed my dentist who extracted one wisdom tooth and giving me same treatment. Now the patch inside cheek has disappeared by 80% by the 5 days while the dose of Vitamin-A was going on. But after completing 5 Vitamin-A capsules, rest 20% of patch is not going away since 1 month. I m too much worried about this. Can you please give me a permanent solution for this problem? Thanks Hasan
