What causes bullous disease?
Bullous pemphigoid is caused by a problem with the immune system (the body’s defence against infection). Instead of attacking germs, it attacks and damages the skin. It’s not known why this happens. Sometimes it’s been linked to skin damage (such as sunburn) or taking certain medicines.
What does pemphigus look like?
Pemphigus affects the outer of the skin (epidermis) and causes lesions and blisters that are easily ruptured. Pemphigoid affects a lower layer of the skin, between the epidermis and the dermis, creating tense blisters that do not break easily. Sometimes pemphigoid may look like hives or eczema without blisters.
What disease causes blisters all over the body?
Pemphigus is a rare group of autoimmune diseases. It causes blisters on the skin and mucous membranes throughout the body. It can affect the mouth, nose, throat, eyes, and genitals. Pemphigus vulgaris is the most common type of pemphigus.
What is the difference between pemphigus and pemphigoid?
Pemphigus is characterized by shallow ulcers or fragile blisters that break open quickly. Pemphigoid presents with stronger or “tense” blisters that don’t open easily. Those with pemphigoid are also more likely to have hot, red and itchy hive spots.
What does a bulla look like?
A bulla is a fluid-filled sac or lesion that appears when fluid is trapped under a thin layer of your skin. It’s a type of blister. Bullae (pronounced as “bully”) is the plural word for bulla. To be classified as a bulla, the blister must be larger than 0.5 centimeters (5 millimeters) in diameter.
What is acantholysis in pemphigus vulgaris?
Abstract. Pemphigus vulgaris is a life-threatening autoimmune blistering disease targeting skin and mucous membranes, characterized by disruption of keratinocytes’ adhesion termed acantholysis.
What are the early signs of pemphigus?
Symptoms
- Pemphigus vulgaris. This type usually begins with blisters in your mouth and then on your skin or genital mucous membranes. The blisters typically are painful but don’t itch.
- Pemphigus foliaceus. This type causes blisters on the chest, back and shoulders. The blisters tend to be more itchy than painful.

- oozing, crusting, or peeling at the blister site.
How does someone get pemphigus?
Pemphigus vulgaris is not fully understood. Experts believe that it’s triggered when a person who has a genetic tendency to get this condition comes into contact with an environmental trigger, such as a chemical or a drug. In some cases, pemphigus vulgaris will go away once the trigger is removed.
