Vulvar Childhood Pemphigoid (VCP)

Vulvar childhood pemphigoid (VCP) is a rare autoimmune disorder that affects the skin and mucous membranes of the vulva in young girls. It is a subtype of bullous pemphigoid, which is characterized by the formation of fluid-filled blisters on the skin and mucous membranes. VCP typically presents in girls under the age of 10, and may be associated with other autoimmune disorders. The exact cause of VCP is not well understood, but it is thought to involve an abnormal immune response to a protein in the basement membrane of the vulvar skin. Treatment typically involves the use of topical or systemic steroids to reduce inflammation and blister formation.


The exact cause of VCP is not known, but there are several factors that are believed to contribute to its development:

  1. Autoimmune response: VCP is thought to be caused by an autoimmune response, in which the body’s immune system mistakenly attacks healthy tissues in the vulvar area. This can lead to inflammation, blistering, and erosion of the skin and mucous membranes.
  2. Genetic factors: Some cases of VCP may be caused by genetic factors, as there is evidence that the condition can run in families. It is believed that certain genes may predispose individuals to develop autoimmune disorders like VCP.
  3. Environmental triggers: Certain environmental triggers may also play a role in the development of VCP, such as exposure to certain chemicals, drugs, or infections. However, the exact nature of these triggers is not well understood.
  4. Hormonal factors: VCP may be influenced by hormonal factors, as it primarily affects girls and can be associated with puberty. However, the exact relationship between hormones and VCP is not clear.
  5. Other autoimmune disorders: VCP may be associated with other autoimmune disorders, such as pemphigus vulgaris or bullous pemphigoid. In some cases, VCP may be a variant of these conditions.

Overall, the exact causes of VCP are not well understood, and more research is needed to fully understand the underlying mechanisms of the condition.


The main symptoms of vulvar childhood pemphigoid include:

  1. Blisters and ulcers: The most common symptom of vulvar childhood pemphigoid is the development of painful blisters and ulcers on the vulva, which can also spread to other areas of the body.
  2. Itching and burning: The affected area may also be itchy and burning, causing discomfort and pain.
  3. Skin thickening: In some cases, the skin around the affected area may become thick and leathery, making it difficult to move or walk.
  4. Scarring: If left untreated, vulvar childhood pemphigoid can cause scarring, which may lead to long-term complications and difficulties.
  5. Painful urination: The blisters and ulcers on the vulva can make urination painful and uncomfortable.
  6. Difficulty with daily activities: The pain and discomfort caused by vulvar childhood pemphigoid can make it difficult to carry out daily activities, such as walking, sitting, or wearing tight-fitting clothing.
  7. Eye involvement: In rare cases, vulvar childhood pemphigoid can also affect the eyes, causing inflammation, redness, and pain.

It is important to seek medical attention if you or your child experiences any of these symptoms. Vulvar childhood pemphigoid can be treated with medications and other therapies, and early treatment can help prevent complications and improve outcomes.


The main test for VCP is a biopsy of the affected area. The biopsy is usually taken from the edge of the blister, and it is examined under a microscope to determine the presence of immune deposits.

The biopsy may also be examined using direct immunofluorescence (DIF) microscopy, which involves the use of a fluorescent dye to highlight the immune deposits. This technique can help to confirm the diagnosis of VCP and differentiate it from other blistering disorders.

In addition to the biopsy and DIF, blood tests may be performed to look for antibodies that target specific proteins in the skin. These antibodies are often present in individuals with VCP and can be used to confirm the diagnosis.

Other tests that may be performed include a skin prick test to identify potential allergens that may be triggering the immune response, and a patch test to evaluate the patient’s sensitivity to various substances.

Overall, the diagnosis of VCP is based on a combination of clinical findings, laboratory tests, and histological examination. Treatment typically involves the use of immunosuppressive medications to control the immune response and prevent further damage to the skin.


The main treatment for vulvar childhood pemphigoid is systemic corticosteroids, such as prednisone, which suppress the immune system and reduce inflammation. This medication is usually taken orally for several weeks or months, with the dose gradually tapered off as symptoms improve.

The main treatment of VCP is aimed at reducing symptoms and preventing complications.

  1. Topical corticosteroids: Mild to moderate cases of VCP can be treated with topical corticosteroids, such as betamethasone or clobetasol, which can reduce inflammation, itching, and pain. These medications are applied to the affected area once or twice a day for several weeks.
  2. Systemic corticosteroids: Severe cases of VCP may require treatment with systemic corticosteroids, such as prednisone or methylprednisolone. These medications are taken orally and can be effective in reducing inflammation and preventing scarring. However, long-term use of corticosteroids can cause side effects, such as weight gain, mood changes, and increased risk of infections.
  3. Immunosuppressive drugs: In some cases, VCP may be treated with immunosuppressive drugs, such as azathioprine or mycophenolate mofetil, which can help to control the immune response that causes the blistering and erosion. These medications are usually reserved for severe cases or cases that do not respond to corticosteroids.
  4. Symptomatic treatment: In addition to medication, symptomatic treatment can also help to relieve symptoms and improve quality of life. This may include using emollients or ointments to soothe the skin, taking painkillers or antihistamines to relieve pain and itching, or using vaginal dilators to prevent scarring and stenosis.
  5. Follow-up care: Children with VCP require regular follow-up care to monitor their symptoms and adjust their treatment as needed. Long-term management may involve tapering off corticosteroids, transitioning to maintenance therapy with immunosuppressive drugs, or considering other treatment options, such as intravenous immunoglobulin or rituximab.

Other immunosuppressive drugs may also be used, such as azathioprine or mycophenolate mofetil, which can help reduce the need for high doses of corticosteroids and their associated side effects.

Topical corticosteroids, such as clobetasol or betamethasone, can also be used to reduce inflammation and itching of the vulva. However, they should be used cautiously and only under the supervision of a healthcare provider, as they can cause thinning of the skin and other side effects.

In addition to medication, good hygiene and wound care are important in managing vulvar childhood pemphigoid. The affected area should be kept clean and dry, and dressings may be needed to protect the skin and promote healing.

Regular follow-up with a healthcare provider is also important, as vulvar childhood pemphigoid can cause long-term complications such as scarring, strictures, and sexual dysfunction. Close monitoring can help detect and manage these issues early.
