[|Human|] On the roof of my mouth it is gray and purple it doesn t hurt what could it be. I went to dentist a week and half ago he didn t say anything about it or if I had it at that time. I have cml and I am on glee vac 400mg once a day Could that have anything to do with it, my primary care doctor didn t know
[|AI|]  Thanks for your query, I have gone through your query. Imatinib desolate (Sleeve) is a protein inhibitor used in the management of several hematological malignancies associated with side effects like hyperpigmentation of the oral mucosa. In your case, the gray and purple spots are because of the side effects of the glee vac 400. Nothing to be panic, it will not trouble you as such, only appearance wise it might bother you. Once you stop the Chat Doctor. I hope my answer will help you, take care.
