Pemphigus Vegetans of Neumann

Pemphigus vegetans of Neumann is a rare and chronic autoimmune disease characterized by the formation of vegetating lesions in the skin and mucous membranes. It is a subtype of pemphigus vulgaris, which is a group of autoimmune disorders that cause blistering and erosions of the skin and mucous membranes.

The disease is caused by the production of autoantibodies that attack the intercellular junctions of the skin and mucous membranes, leading to their separation and the formation of blisters. The blisters eventually rupture, leaving behind raw, oozing patches of skin that are vulnerable to secondary infections.


The exact cause of the disease is unknown, but there are several factors that can trigger or contribute to the development of the disease. The following are the main causes of Pemphigus vegetans of Neumann:

  1. Genetic Factors: Pemphigus vegetans is believed to be a genetic disease, meaning that it is passed down from one generation to the next. Several genes have been identified that are associated with the development of the disease. These genes are involved in the production of proteins that are important for the function of the immune system.
  2. Autoimmune Reaction: Pemphigus vegetans is an autoimmune disease, which means that the body’s immune system attacks its own tissues. In Pemphigus vegetans, the immune system produces antibodies that attack proteins in the skin and mucous membranes, causing blisters to form.
  3. Infections: In some cases, infections can trigger the development of Pemphigus vegetans. Certain viruses, bacteria, and fungi have been linked to the disease, and it is believed that they may activate the immune system and trigger an autoimmune reaction.
  4. Medications: Some medications have been linked to the development of Pemphigus vegetans. These include drugs used to treat high blood pressure, heart disease, and autoimmune diseases.
  5. Environmental Factors: Exposure to certain environmental factors, such as ultraviolet light, can trigger the development of Pemphigus vegetans. It is believed that these factors may activate the immune system and trigger an autoimmune reaction.

In conclusion, Pemphigus vegetans is a complex disease that can be caused by a combination of genetic, environmental, and autoimmune factors. While the exact cause of the disease is still unknown, it is important to identify and address any potential triggers in order to effectively manage the symptoms of the disease.


The main symptoms of this condition include:

  1. Blisters and ulcers: Pemphigus vegetans usually starts with the formation of small blisters or pustules on the skin or mucous membranes, such as the mouth, throat, or genital area. These blisters can break and form painful ulcers that can ooze pus or other fluids.
  2. Vegetative lesions: In some cases, the blisters and ulcers may develop into vegetative lesions, which are thick, raised, and wart-like growths that can resemble cauliflower. These lesions can be very itchy and can cause discomfort.
  3. Erosions and crusts: As the disease progresses, the blisters and ulcers can spread and merge, leading to the formation of erosions and crusts.
  4. Skin lesions: Pemphigus vegetans typically presents as pus-filled blisters or sores on the skin. The lesions may be located in areas such as the armpits, groin, and skin folds.
  5. Vegetative growths: As the name suggests, Pemphigus vegetans is characterized by the growth of fleshy, cauliflower-like masses in the affected areas. These growths can be quite extensive and may merge with each other, forming large plaques.
  6. Itching and pain: The lesions and vegetative growths associated with Pemphigus vegetans can be very itchy and painful.
  7. Mucosal involvement: In some cases, Pemphigus vegetans may also affect the mucous membranes of the mouth, nose, and genital area. This can result in painful sores and ulcers in these areas.

The diagnosis of Pemphigus vegetans is based on clinical presentation and confirmed by histopathology and direct immunofluorescence.

Histopathology is an examination of the skin tissue under a microscope. It reveals acantholysis, which is the loss of cohesion between skin cells, leading to the formation of a blister. Direct immunofluorescence involves taking a skin biopsy and staining it with specific antibodies. This test confirms the presence of immunoglobulin G (IgG) and complement C3 in the affected tissue.

Other tests that may be performed include serology for anti-desmoglein antibodies, which are specific to Pemphigus, and a biopsy of the mucous membrane. The biopsy of the mucous membrane is useful in differentiating between Pemphigus vegetans and Pemphigus vulgaris, which is a more common form of Pemphigus.

In summary, the diagnosis of Pemphigus vegetans is made based on clinical presentation, histopathology, and direct immunofluorescence. Additional tests, such as serology for anti-desmoglein antibodies and mucous membrane biopsy, may be necessary to differentiate it from other forms of Pemphigus.


The main treatment for Pemphigus vegetans of Neumann involves a combination of corticosteroids, immunosuppressive drugs, and antibiotics.

Corticosteroids are the first-line treatment for Pemphigus vegetans. They are used to reduce inflammation and suppress the immune system. High doses of oral prednisone or intravenous methylprednisolone are often used to control the disease. However, long-term use of corticosteroids can lead to side effects such as weight gain, diabetes, and osteoporosis.

Immunosuppressive drugs are also used to treat Pemphigus vegetans. These drugs work by suppressing the immune system to reduce inflammation and prevent the formation of new blisters. Azathioprine, mycophenolate mofetil, and cyclosporine are some of the commonly used immunosuppressive drugs.

In addition to corticosteroids and immunosuppressive drugs, antibiotics are also used to treat Pemphigus vegetans. Antibiotics are used to prevent secondary infections that may occur due to the open sores caused by the disease. Topical antibiotics such as mupirocin can be used for localized infections, while oral antibiotics such as doxycycline or clarithromycin may be used for more widespread infections.

In severe cases of Pemphigus vegetans, intravenous immunoglobulin (IVIG) may be used. IVIG is a blood product that contains high levels of antibodies that can help to suppress the immune system and reduce inflammation. However, IVIG is expensive and can cause side effects such as headache, fever, and allergic reactions.

In conclusion, the main treatment for Pemphigus vegetans of Neumann involves a combination of corticosteroids, immunosuppressive drugs, and antibiotics. Treatment should be individualized based on the severity of the disease, the patient’s age, and overall health. Regular monitoring and follow-up with a dermatologist or autoimmune disease specialist are essential for effective management of the disease.
