Signs of Pemphigus Vulgaris

The blisters can break easily, leaving erosions that are sore, moist, or crusted rather than intact for long. Mouth lesions may affect the gums, cheeks, palate, tongue, or throat and can make eating, drinking, or swallowing difficult. Skin sores may appear on the chest, back, face, scalp, or other areas; some are tender or itchy. Symptoms may be mistaken for infection or another blistering disorder. Diagnosis requires medical examination and may involve skin tests or a biopsy, so self-treatment alone is not enough.

Arrange prompt assessment by a dermatologist, particularly when mouth sores recur or skin blisters keep appearing. Use gentle cleansing, avoid rubbing fragile skin, and choose soft foods and cool drinks if the mouth is sore. Do not deliberately burst blisters or apply strong products without advice. Specialist treatment can include Oral Corticosteroid Treatment or Biologic Therapy, depending on the diagnosis, severity, and other health factors.

Seek urgent care if you cannot drink, pass very little urine, feel faint, have extensive open sores, develop fever, or notice spreading redness, warmth, pus, or severe pain. Breathing difficulty or swelling of the throat requires emergency help. Open erosions can lose protective skin and make dehydration or infection a concern, so worsening symptoms should not wait for a routine review.

Do my mouth or skin sores need a biopsy or specialist testing? How can I protect open areas and maintain nutrition? What monitoring is needed with treatment, and which changes should prompt urgent contact?
