Acquired Epidermolysis Bullosa (EBA)

Acquired epidermolysis bullosa (EBA) is a rare autoimmune skin disease. “Autoimmune” means your immune system accidentally attacks part of your own body. In EBA, the immune system makes antibodies against type VII collagen, a strong “anchor” protein that holds the top layer of skin (epidermis) to the layer underneath (dermis). When these anchors are attacked, the skin becomes fragile. Even small rubbing or bumps can cause tense blisters, raw areas, and later scars or tiny white cysts called milia. EBA can also affect the mouth, eyes, nose, throat, and esophagus (the swallowing tube). It usually starts in adults, and it is not inherited. NCBIDermNet®rarediseases.info.nih.gov

Acquired epidermolysis bullosa—usually called epidermolysis bullosa acquisita (EBA)—is a rare autoimmune skin disease. Your immune system mistakenly makes antibodies against type VII collagen, a key protein that anchors the top layer of skin (epidermis) to the layer below (dermis). When those anchors are attacked, the skin becomes very fragile. Even small friction can cause tense blisters, raw erosions, scars, milia (tiny white cysts), and nail loss. The hands, feet, elbows, knees, and buttocks are common sites because they get more bumps and pressure. The mouth, nose, eyes, throat, and esophagus can also be involved, which may affect eating, speaking, and vision. Unlike inherited forms of epidermolysis bullosa (present from birth), EBA is not genetic and usually starts in adults. NCBIDermNet®rarediseases.info.nih.gov

Doctors diagnose EBA with a skin biopsy and special tests: direct immunofluorescence (a glowing line along the skin’s basement membrane), salt-split skin testing (antibodies bind the dermal “floor”), serologic tests (ELISA/immunoblot for anti–type VII collagen), and serration-pattern analysis (a “u-serrated” pattern that helps distinguish EBA from similar diseases like bullous pemphigoid). These tests often need an experienced lab. PubMed Central+1FrontiersDermNet®Lippincott Journals

Other names

• Epidermolysis bullosa acquisita (EBA)

• Acquired epidermolysis bullosa

• Autoimmune anti–type VII collagen blistering disease

• EBA—mechanobullous type (classic, scar-forming pattern)

• EBA—inflammatory type (looks like bullous pemphigoid)

• Mucous membrane EBA (when eyes, mouth, or throat are mainly involved)

• Brunsting–Perry–like EBA (a localized scarring pattern in the head/neck) Medical JournalsPubMed

In healthy skin, type VII collagen builds anchoring fibrils—tiny ropes that connect the top skin layer to the layer below. In EBA, antibodies stick to type VII collagen and call in inflammatory cells. This weakens the anchors and skin layers split underneath the epidermis (subepidermal blister). The blister roof is thick, so blisters feel tense. With time, healing leaves scars and milia (small white bumps). Where the skin gets rubbed a lot—hands, feet, elbows, knees, buttocks—blisters are common. If the mouth, eyes, or throat are involved, people may have pain with eating, hoarseness, dry eyes, or swallowing trouble. NCBIDermNet®

Types

Doctors group EBA by how it looks on the skin and mucosa. One person can have more than one pattern.

1. Mechanobullous (classic) EBA
   This is the scar-forming type. Blisters appear on areas that get friction and minor injuries. They heal with scars and milia, and nails may become thick or lost. It can mimic inherited dystrophic EB, but it starts in adult life. NCBI

2. Inflammatory (BP-like) EBA
   Blisters happen on normal or red, itchy skin and can look like bullous pemphigoid. Mucosa can be involved. Less scarring than the classic type. NCBI

3. Mucous membrane (cicatricial) EBA
   Mainly eyes, mouth, nose, throat, or genitals. Repeated blisters and erosions leave scars, which can cause eye adhesions (symblepharon) or esophageal narrowing. Medical Journals

4. Brunsting–Perry–like EBA
   Localized, scarring blisters on the head and neck that resemble Brunsting–Perry pemphigoid, but the autoantigen is type VII collagen. PubMed

5. IgA-mediated EBA (rare)
   Antibodies are IgA instead of the usual IgG, but they still target type VII collagen. Medscape

Causes

EBA has one root cause and many associated or triggering factors. The true cause is your immune system making anti–type VII collagen antibodies. The items below explain that core cause and list recognized contributors, links, or reported triggers. (Doctors may not find a single trigger in many patients.)

1. Autoimmunity to type VII collagen – the main cause; antibodies attack the anchoring fibrils and separate skin layers. NCBI

2. Genetic immune risk (HLA class II) – several studies show more HLA-DR2 / HLA-DRB1*15 in EBA, suggesting a background tendency to autoimmunity. PubMedFrontiers

3. Mechanical friction/trauma – not the root cause, but often triggers new blisters in fragile skin (hands, feet, elbows, knees, buttocks). DermNet®

4. Inflammatory bowel disease (IBD), especially Crohn’s disease – many case series report a link; the gut also has type VII collagen. (Note: newer matched studies question whether IBD is a true risk factor rather than a coincidence.) FrontiersMedscapePubMed Central

5. Systemic lupus erythematosus (SLE) – some patients with SLE develop an EBA-like blistering disease targeting type VII collagen. Medscape

6. Other immune dysregulation – epitope spreading and complement activation can maintain the antibody attack and blistering. Medscape

7. Older age – EBA is more common in adulthood and older adults, which may reflect age-related immune changes. MDPI

8. Mucosal irritation (mouth, eyes, throat) – local trauma from dental work, spicy or sharp foods, or rubbing may provoke new lesions in susceptible mucosa. DermNet®

9. Infections as immune triggers – infections can sometimes wake up the immune system and flare autoimmune diseases; specific proof in EBA is limited but biologically plausible. (General autoimmune mechanism.) Medscape

10. Drugs (rare case reports) – antibiotics (e.g., vancomycin) and other medicines have been reported in isolated cases before EBA onset. ScienceDirect

11. Severe drug reactions (DRESS) – EBA has been reported after drug-induced hypersensitivity (e.g., lamotrigine DRESS), suggesting a strong immune trigger. PubMed Central

12. Vaccination as an immune trigger (rare) – isolated reports describe EBA flare after mRNA COVID-19 vaccination; this is uncommon and does not prove causation. Frontiers

13. Esophageal reflux or chronic mucosal inflammation – irritation can worsen mucosal disease in people with EBA. (Clinical inference from mucosal EBA.) Medical Journals

14. Ultraviolet (sun) exposure – UV can aggravate many autoimmune blistering diseases; patients often report flares after sunburn or strong sun. (General AIBD guidance.) Frontiers

15. Surgery or procedural trauma – skin or mucosal procedures may trigger new lesions at injury sites because the skin is fragile. DermNet®

16. Smoking-related irritation – smoke can irritate oral mucosa and delay wound healing, worsening mouth lesions (general wound-healing factor). Frontiers

17. Nutritional stress and poor wound care – poor protein or micronutrient intake can slow healing of blisters/erosions (general wound science). Frontiers

18. Comorbid blood or plasma cell disorders – rare reports with amyloidosis and multiple myeloma appear in rare-disease summaries. rarediseases.info.nih.gov

19. Immune checkpoint inhibitor therapy (rare) – modern cancer immunotherapy has isolated case reports of EBA-like disease. ejcskn.com

20. Family immune tendency – EBA itself is not inherited, but family clusters and HLA data suggest a genetic susceptibility to making these antibodies. Frontiers

4. Itching (especially in the inflammatory type). NCBI

5. Scars after healing; skin can look thin, shiny, or tight. NCBI

6. Milia—tiny white cysts that appear in old healed areas. ScienceDirect

7. Nail changes—thickened, brittle, or missing nails. ScienceDirect

8. Mouth sores—painful erosions that make eating or toothbrushing hard. DermNet®

9. Hoarseness or sore throat when the voice box or throat mucosa is affected. Medical Journals

10. Eye irritation—redness, pain, light sensitivity; repeated flares can lead to scarring (symblepharon). Medical Journals

11. Swallowing trouble or food “sticking” if the esophagus scars or narrows. Medical Journals

12. Genital discomfort from erosions or scarring. Medical Journals

13. Slow healing of wounds and frequent infections in broken skin.

14. Reduced hand/foot function when scars or pain limit movement.

15. Emotional stress and poor sleep due to pain, itch, and the burden of dressings.

Diagnostic tests

Important: doctors diagnose EBA by putting together the story, the skin exam, skin biopsy, and immunology tests. A few tests below are essential; others help check mucosal damage or rule out look-alike diseases. Electro-diagnostic tests are not standard for EBA.

A) Physical examination (how the doctor looks and checks)

1. Full-skin inspection
   The doctor looks for tense blisters, erosions, scars, and milia, especially on trauma-prone areas (hands, feet, knees, elbows, buttocks). Pattern helps suspect EBA. DermNet®

2. Mucosal examination
   Mouth, nose, eyes, throat, and genitals are checked for blisters, erosions, and scarring. This can point to mucous membrane EBA. Medical Journals

3. Nail examination
   Nails are reviewed for thickening, ridging, or loss, which supports a long-standing, scar-forming process. ScienceDirect

4. Photographic mapping
   Photos record where lesions are; this helps track healing or new blisters after friction or procedures.

5. Assessment of functional impact
   Doctors ask about pain, itch, eating, vision, and swallowing to capture how mucosal involvement affects daily life.

B) Manual bedside signs

6. Nikolsky sign (gentle rubbing)
   Gentle sideways rubbing may or may not extend the blister edge in EBA. It is not a reliable rule-in or rule-out sign for this disease but is often checked.

7. Asboe-Hansen sign (bulla spread)
   Gentle pressure on the blister roof looks for spreading under the skin. This can occur in many blistering diseases and is non-specific.

8. Friction-provocation check
   Doctors sometimes note whether repeated friction at the same site leads to new tense blisters in fragile areas—this supports a mechanobullous pattern. DermNet®

C) Laboratory & pathological tests

9. Routine hematology/chemistry
   Looks for infection, anemia, or treatment safety needs. Not specific for EBA, but important for care.

10. Skin biopsy for H&E (light microscopy)
    Taken from the edge of a fresh blister, it usually shows a subepidermal split (the roof is full-thickness epidermis) with mixed inflammatory cells depending on the type. This says “where the skin split,” but not “why.” Taylor & Francis Online

11. Direct immunofluorescence (DIF) of perilesional skin
    This is a key test. It often shows a linear band of IgG (and sometimes C3) along the basement membrane zone. In EBA, a special “u-serrated” pattern on DIF supports the diagnosis and helps separate EBA from pemphigoid (which tends to have an “n-serrated” pattern). MedscapeEuroimmun Polska

12. Salt-split skin mapping (DIF/IIF on “salt-split” substrate)
    The lab “splits” skin at the basement membrane. In EBA, antibodies bind the dermal (“floor”) side, because type VII collagen sits beneath the split. This is very helpful to tell EBA from bullous pemphigoid. jaadcasereports.org

13. Serum ELISA for anti–type VII collagen (NC1/NC2)
    A blood test that directly measures antibodies to type VII collagen. ELISA is highly useful and often more sensitive than some other methods. ARUP Consult

14. Immunoblot/Western blot
    Detects antibodies to specific pieces of type VII collagen (like NC1 or NC2). Used when ELISA or IIF are unclear. ScienceDirect

15. BIOCHIP® mosaic panels (AIBD profiles)
    Modern lab slides allow side-by-side screening for multiple skin autoantibodies; reading may also show the u-serrated clue. Euroimmun Polska

16. Electron microscopy (EM)
    Shows fewer or damaged anchoring fibrils attaching epidermis to dermis. EM supports the mechanism but is not required in most cases. PubMed Central

17. Complement and inflammatory markers
    Not specific for EBA, but they can support active inflammation and help guide treatment safety.

D) Electro-diagnostic tests

18. Electro-diagnostic studies
    There is no standard electro-diagnostic test for EBA. Nerve or muscle tests (EMG/nerve conduction) do not diagnose EBA; they are used only if other problems are suspected. (Dermatology guidelines for AIBD do not include electro-diagnostics.) ARUP Consult

E) Imaging & endoscopic tests

19. Eye (slit-lamp) examination
    An ophthalmologist checks for eye surface damage and scarring (symblepharon) if the eyes are involved—crucial to prevent vision loss. Medical Journals

20. Upper endoscopy or barium swallow (esophagram)
    Looks for erosions or narrowing in the esophagus when swallowing is hard. This helps plan diet changes or dilations. Medical Journals

• Iron-rich foods (meat, beans, leafy greens) if iron-deficient—confirm with labs.

• Vitamin C sources (citrus, guava, kiwi, bell peppers) for collagen.

• Zinc sources (meat, legumes, seeds) for epithelial repair.

• Vitamin D & calcium sources (dairy/fortified alternatives) to protect bones during steroids.

• Omega-3 sources (fatty fish, flaxseed) for inflammation balance.

• Soft fruits/vegetables (stews, soups) to avoid mucosal trauma.

• Plenty of fluids to support healing.

• Doctor-approved oral nutrition supplements if intake is poor. DEBRA InternationalSchn Health

Foods/habits to avoid or limit

• Sharp/crusty foods (chips, crusty bread) that cut oral mucosa.

• Very spicy/acidic items (hot chilies, vinegar, citrus juices) during mouth flares.

• Alcohol (irritates mucosa; interacts with medicines).

• Hard, sticky candies (trauma; dental risk).

• Smoking/tobacco (slows healing).

• Excess added sugar (glycemic spikes on steroids, poorer wound repair).

• Very hot beverages/soups (thermal injury).

• Harsh mouthwashes with alcohol.

• Unverified supplements that interact with immunosuppressants.

• Fad restrictive diets that cut needed protein/micronutrients. Medscape

Frequently Asked Questions

1. Is EBA genetic?
   No. EBA is acquired and autoimmune; inherited EB is different. DermNet®

2. What exactly is my body attacking?
   Type VII collagen in anchoring fibrils that hold skin layers together. NCBI

3. Why do blisters appear where I rub my skin?
   Friction triggers separation when the anchors are weakened by antibodies. DermNet®

4. How is EBA confirmed?
   Biopsy with direct immunofluorescence, salt-split testing (dermal-floor binding), and blood tests for anti–type VII collagen; serration-pattern analysis helps distinguish EBA. PubMed Central+1DermNet®

5. What are the main treatment goals?
   Prevent new trauma, heal wounds, and suppress the autoimmune attack. Medscape

6. Will I need steroids?
   Often at first for control; your team will taper and switch to steroid-sparing medicines if possible. Medscape

7. Are there modern targeted drugs?
   Yes—rituximab and IVIG help many refractory cases. New options (FcRn and complement inhibitors) are under study. PubMed Central+1

8. Can diet really help?
   Yes—higher protein and calories plus key micronutrients support wound healing and immunity; a dietitian can tailor this. DEBRA International

9. How do I pop blisters safely?
   Use sterile technique to drain at the edge and leave the roof in place; then cover with a non-adherent dressing. debra.org

10. Why do I need eye and mouth specialists?
    Mucosal scarring can threaten vision, swallowing, and speech; early care prevents disability. Medscape

11. Is EBA linked to other diseases?
    Some patients have Crohn’s disease or lupus; treating those can help the skin. rarediseases.info.nih.gov

12. How long does treatment last?
    Months to years. Some patients reach remission; others need ongoing maintenance and flare management. Medscape

13. Can I exercise?
    Yes—with protection and low-friction strategies guided by PT/OT. Benefits include strength, balance, and mood.

14. What about pregnancy?
    Plan ahead with your dermatology/OB team—some medicines are unsafe in pregnancy and need switches.

15. Where can I find reliable resources?
    DermNet, GARD, DEBRA International wound-care/nutrition guidance, and specialist centers. DermNet®rarediseases.info.nih.govDEBRA International
