Pityriasis Lichenoides Chronica - Symptoms and Treatment
Pityriasis lichenoides is a rash with red or brown, raised, scaly patches that can form scarsLesions may self-involute and resolve completely over weeks, or new lesions occasionally may appear in crops, waxing and waning spontaneously for months to years thereafter. The condition can range from a relatively mild chronic form to a more severe acute eruption. The term Pityriasis lichenoides describes a spectrum of skin disorders which range from relatively benign mild, scaly papules, to more severe acute papular eruptions. The aetiology of the disorder is not yet known, however there appears to be an association with some types of infection e.g. Epstein -Barr virus and Toxoplasma gondii. The chronic form shows elevated, reddened, dome-shaped papules in a symmetrical distribution, which enlarge, flatten, and show a fine scale on their surface. The disease can run over weeks, months, or even years, with lesions continually appearing and disappearing. The disease is most common in males and usually accures in childhood, although it has been seen in every race and age group. It is not contagious and currently there is no cure for the disease, although the lesions can be treated with ultraviolet therapy as well as topical steroids and antibiotics. The awkward name 'pityriasis lichenoides' means that the rash is scaly (pityriasis) and that it was once thought to look a bit like lichen because it is made up of small bumpy areas.
Pityriasis lichenoides is probably a hypersensitivity reaction to a microorganism. Pityriasis lichenoides encompasses a spectrum of clinical presentations ranging from acute papular lesions that rapidly evolve into pseudovesicles and central necrosis to small, scaling, benign-appearing papules. The milder form of the disorder known as pityriasis lichenoides chronica is associated with small, scaling papules whilst at the other end of the spectrum, the more severe pityriasis lichenoides et varioliformis acuta is associated with an acute onset of papular lesions which progress to pseudovesicles with areas of central necrosis. Pityriasis lichenoides is probably a hypersensitivity reaction to a microorganism. Pityriasis lichenoides is an inflammatory disease, which is characterized by acute and/or chronic morphological phases and epidermal shedding of flaky scales. The disease can run over weeks, months, or even years, with lesions continually appearing and disappearing. The chronic form of the disease is called pityriasis lichenoides chronica. It is also accompanied by recurrent erythematous, round papules, hemorrhage, blisters and varioliform vesiculopustules.
