Pityriasis lichenoides et varioliformis acuta

From WikiMD's Wellnesspedia

Pityriasis Lichenoides et Varioliformis Acuta (PLEVA) is a rare skin disorder that is characterized by the sudden onset of small, red, scaling patches that can evolve into blisters or pustules. It is often abbreviated as PLEVA and is also known as Mucha-Habermann disease.

Symptoms[edit | edit source]

The symptoms of PLEVA include rashes, itching, and fevers. The rashes are usually small, red, and scaly, and they can evolve into blisters or pustules. The rashes can appear anywhere on the body, but they are most commonly found on the trunk, arms, and legs. The itching can be mild to severe, and it is often worse at night. The fevers are usually low-grade, but they can be higher if the disease is severe.

Causes[edit | edit source]

The exact cause of PLEVA is unknown, but it is thought to be an abnormal immune response to a viral or bacterial infection. Some researchers believe that it may be triggered by certain medications, such as antibiotics, nonsteroidal anti-inflammatory drugs, and vaccines.

Diagnosis[edit | edit source]

The diagnosis of PLEVA is usually based on the appearance of the skin lesions and the history of the symptoms. A skin biopsy may be performed to confirm the diagnosis. The biopsy usually shows a characteristic pattern of inflammation in the skin.

Treatment[edit | edit source]

The treatment of PLEVA is aimed at relieving the symptoms and preventing complications. This may include topical corticosteroids, antihistamines, and antibiotics. In severe cases, phototherapy or immunosuppressive drugs may be used.

Prognosis[edit | edit source]

The prognosis of PLEVA is generally good, but it can vary depending on the severity of the disease and the response to treatment. Most people with PLEVA recover completely within a few months, but some may have recurrent episodes.
