Pityriasis Lichenoides Information: Pityriasis Lichenoides Chronica

What are Pityriasis Lichenoides

Pityriasis lichenoides is probably a hypersensitivity reaction to a microorganism. No specific bacteria or virus has yet been identified however. It is not considered to be contagious. Pityriasis lichenoides is a rare cutaneous disorder of unknown etiology. Pityriasis lichenoides encompasses a spectrum of clinical presentations ranging from acute papular lesions that rapidly evolve into pseudovesicles and central necrosis (pityriasis lichenoides et varioliformis acuta or PLEVA) to small, scaling, benign-appearing papules (pityriasis lichenoides chronica or PLC).

Most often, the lesions occur on the trunk, thighs and the inner aspect of the upper arms. Pityriasis lichenoides rarely affects the face or scalp, but it can arise at any other site. It may last for months or even several years, with crops of new lesions appearing every few weeks.

Pityriasis Lichenoides Chronica

Pityriasis Lichenoides mild form is known as pityriasis lichenoides chronica (PLC). The more severe form is known as pityriasis lichenoides et varioliformis acuta (PLEVA), also known as Mucha-Haberman disease. The chronic form is more scaly and less hemorrhagic. There is a predilection for males in the second and third decades. They are most common on the anterior trunk and flexor surfaces of the proximal portions of the extremities.

Pityriasis Lichenoides Cause

Pityriasis Lichenoides is characterized by the abrupt onset of a generalized, reddish-brown, maculopapular eruption. Lesions may be vesicular, hemorrhagic, crusted, or necrotic. Histologically the disease is characterized by epidermal necrolysis. The chronic form shows milder skin changes with necrosis.

Pityriasis Lichenoides Treatment

Here are the list of Pityriasis Lichenoides Treatment:

• Corticosteroid creams and ointments applied to the skin often control the rash and itching.
• Antihistamines such as Benadryl by mouth will help alleviate the itching.
• The disease can be controlled but not cured.
• Sometimes ultraviolet light treatment will improve pityriasis lichenoides.
