What is Pityriasis lichenoides et varioliformis acuta

Pityriasis lichenoides et varioliformis acuta (PLEVA) is a rare skin disorder characterized by the development of small, red, scaly papules on the skin. It primarily affects children and young adults, with a peak incidence between the ages of 10 and 30. The exact cause of PLEVA is unknown, but it is believed to be related to an abnormal immune response.

The main symptoms of PLEVA include the appearance of multiple papules that may evolve into vesicles or pustules. These lesions often have a "volcanic" or "cigarette paper" appearance. They can be itchy and may cause discomfort. PLEVA can occur all over the body, but it is most commonly found on the trunk, limbs, and buttocks.

The course of PLEVA is variable, with some cases resolving spontaneously within a few months, while others may persist for years. Treatment options for PLEVA include topical corticosteroids, phototherapy, and systemic medications such as antibiotics or immunosuppressants. Regular follow-up with a dermatologist is important to monitor the condition and adjust treatment as needed.

Pityriasis lichenoides et varioliformis acuta is a challenging condition that requires proper diagnosis and management to alleviate symptoms and improve the quality of life for those affected.
