Pityriasis Lichenoides et Varioliformis Acuta: Causes, Symptoms, and Diagnosis

Pityriasis lichenoides et varioliformis acuta (PLVA) is a rare skin disorder characterized by the development of small, reddish-brown papules or pimples on the skin. Although the exact cause of PLVA is unknown, it is believed to be an abnormal immune response to certain infections or medications.

PLVA typically affects children and young adults, although it can occur at any age. The condition usually starts with the sudden onset of multiple small, scaly patches that gradually evolve into papules or pustules. These lesions may be itchy or painful and can appear anywhere on the body, including the trunk, limbs, and face.

The diagnosis of PLVA is based on the clinical appearance of the lesions and a thorough medical history. In some cases, a skin biopsy may be performed to confirm the diagnosis. The biopsy involves the removal of a small piece of affected skin for microscopic examination.
