Pityriasis lichenoides chronica (also known as "Chronic guttate parapsoriasis," "Chronic pityriasis lichenoides," "Dermatitis psoriasiformis nodularis," "Parapsoriasis chronica," and "Parapsoriasis lichenoides chronica" "PLC") is an uncommon, idiopathic, acquired dermatosis, characterized by evolving groups of erythematous, scaly papules that may persist for months.[1]:456[2]:737

Contents

Causes

Pityriasis lichenoides chronica (PLC) is probably caused by a hypersensitivity reaction to infectious agents such as the Epstein-Barr virus. Other infectious agents include the adenovirus and parvovirus B19. [3]

Symptoms

Although other forms of the disease occur at younger ages, some individuals start having long term symptoms at thirty years of age. This disease also affects adolescents and young adults. This also affects the immune system which therefore results into rashes. The symptoms rarely affect the face or scalp, but occurs at other sites of the body. The duration may last for months or even several years. For instance, new crops of lesions appear every few weeks. [4]

Treatment

There is no standard treatment for PLC. Treatments may include ultraviolet phototherapy, topical steroids, sun exposure, oral antibiotics, corticosteroid creams and ointments to treat rash and itching. [5] [6]
