Pemphigoid: Symptoms and Treatments
Pemphigoid is a group of rare autoimmune blistering skin diseases that can be life-altering for those affected.
Pemphigoid encompasses various subtypes, each characterized by the formation of blisters on the skin and mucous membranes. Unlike pemphigus, which affects the skin's upper layers, pemphigoid targets the deeper layers, leading to more robust and less fragile blisters.
Types of Pemphigoid
- Bullous Pemphigoid: The most common form, primarily affecting older adults.
- Mucous Membrane Pemphigoid: Affects mucous membranes, including the eyes, mouth, and genitals.
- Pemphigoid Gestationis: Specifically occurs during pregnancy.
Symptoms of Pemphigoid
General Symptoms
Pemphigoid symptoms can vary depending on the type but generally include:
- Blisters: Large, fluid-filled blisters that do not easily rupture.
- Itching: Intense itching often precedes blister formation.
- Redness: Inflamed, red skin around the blister sites.
Bullous Pemphigoid Symptoms
Bullous pemphigoid primarily affects the skin and presents with:
- Widespread Blisters: Typically on the lower abdomen, upper thighs, and forearms.
- Pain: Blisters can cause discomfort, particularly if they become infected.
- Erosions: Once blisters rupture, they leave behind erosions that may take time to heal.
Mucous Membrane Pemphigoid Symptoms
This type affects mucous membranes and can be more severe:
- Oral Lesions: Painful blisters in the mouth that can affect eating and speaking.
- Ocular Lesions: Blisters in the eyes, potentially leading to scarring and vision loss.
- Genital Lesions: Blisters on the genitals causing discomfort and pain.
Pemphigoid gestationis Symptoms
Pemphigoid gestationis appears during pregnancy and includes:
- Abdominal Blisters: Blisters often start around the navel and spread to other areas.
- Itching: Severe itching that can disrupt daily activities.
- Postpartum Persistence: Symptoms may continue even after childbirth.

Get A Second OpinionCauses of Pemphigoid
Pemphigoid is an autoimmune disorder where the body's immune system mistakenly attacks healthy tissue. The exact cause remains unclear, but several factors may contribute:
Genetic Predisposition
A genetic predisposition can increase the risk of developing pemphigoid. Certain genes associated with immune system regulation may play a role.
Environmental Triggers
Environmental factors such as infections, medications, and physical trauma can trigger pemphigoid in genetically predisposed individuals.
Hormonal Changes
In the case of pemphigoid gestationis, hormonal changes during pregnancy are believed to play a significant role in triggering the condition.
Diagnosing Pemphigoid
Clinical Examination
The first step in diagnosing pemphigoid is a thorough clinical examination. Dermatologists look for characteristic blisters and review the patient's medical history.
Skin Biopsy
A skin biopsy is crucial for confirming the diagnosis. A small sample of the affected skin is examined under a microscope to detect antibodies deposited in the skin layers.
Blood Tests
Blood tests can identify circulating antibodies specific to pemphigoid, aiding in the diagnosis and differentiation from other blistering diseases.

Book an AppointmentTreatment Options for Pemphigoid
Treating pemphigoid requires a multifaceted approach tailored to the severity and type of the disease. The primary goals are to reduce inflammation, control symptoms, and prevent complications.
Corticosteroids
Corticosteroids are the cornerstone of pemphigoid treatment. They can be administered topically, orally, or via injection to reduce inflammation and suppress the immune response.
Immunosuppressive Agents
For patients who do not respond adequately to corticosteroids or have severe disease, immunosuppressive agents such as azathioprine, methotrexate, or mycophenolate mofetil may be prescribed.
Biologic Therapies
Biologic therapies targeting specific components of the immune system, such as rituximab, have shown promise in treating refractory pemphigoid cases.
Antibiotics
Secondary infections can complicate pemphigoid, necessitating the use of antibiotics to treat or prevent bacterial infections.
Supportive Care
Skincare
Proper skincare is essential to prevent infections and promote healing. This includes gentle cleansing, using emollients, and avoiding irritants.
Pain Management
Pain management strategies, including analgesics and topical pain relievers, can help alleviate discomfort associated with blisters and erosions.
Nutritional Support
Severe cases, mainly mucous membrane pemphigoid, may require nutritional support if oral intake is compromised. This can include soft diets, dietary supplements, or even feeding tubes in extreme cases.
Living with Pemphigoid
Monitoring and Follow-Up
Regular follow-up with healthcare providers is crucial for monitoring disease progression and adjusting treatment plans as needed.
Patient Education
Educating patients about their condition, treatment options, and self-care practices empowers them to manage their disease effectively.
Psychological Support
Living with a chronic condition like pemphigoid can be emotionally challenging. Access to psychological support and counselling can help patients cope with the stress and anxiety associated with the disease.
Frequently Asked Questions
1. What causes pemphigoid?
Pemphigoid is caused by an autoimmune reaction where the immune system mistakenly attacks healthy skin.
2. What are the symptoms of pemphigoid?
Symptoms include large, fluid-filled blisters primarily on the arms, legs, and abdomen.
3. How is pemphigoid diagnosed?
Pemphigoid is diagnosed through skin biopsies and blood tests to detect antibodies.
4. What treatments are available for pemphigoid?
Treatments include corticosteroids and immunosuppressive medications to reduce inflammation.
5. Is pemphigoid curable?
While pemphigoid can be controlled, there is no definitive cure, and long-term management may be required.
