I had a chronic case of oral papillomatous lesions whose picture is quite similar to your photo. I want to discuss this case with you. These lesions are present in him about since birth and he is undergoing treatment from a pediatric surgeon with some monthly injections and oral medications for last 5 years, but with no significant improvement. A pediatric surgeon prior to him diagnosed him as angioma of cheeks.
