Thanks for writing to us.
These mouth ulcers or erosions could be aphthous ulcers
, pemhigus vulgaris lesions or oral lichen planus
lesions or ulcers in association with any other auto immune disease. Diagnosis requires biopsy
of the lesions. YOu need to consult an ENT doc as well as a dermatologist
. I would be able to help you out more if you could send us a detailed clinical history regarding duration onset appearance of the lesion along with biopsy report.
