Persistent mouth sores can be frustrating, painful, and deeply concerning—especially when they refuse to heal. While many ulcers are caused by minor irritations or viral infections, some may be a sign of something more serious. Among the rarer yet more severe causes is pemphigus vulgaris, an autoimmune condition that often begins with painful, non-healing blisters or erosions in the mouth before affecting other parts of the body.
Pemphigus vulgaris is frequently misdiagnosed in its early stages because its symptoms mimic those of more common conditions like aphthous ulcers or oral thrush. However, catching it early is critical, as the disease can rapidly progress and lead to severe complications without proper treatment. In this article, we’ll explore the symptoms, causes, and diagnosis of pemphigus vulgaris—plus how to differentiate it from other causes of stubborn mouth sores and what to do if you suspect this rare but serious disease.
