Typical treatment includes using topical steroids to reduce the inflammation and reducing exposure to allergens that may be causing or worsening the condition. One key feature of PLC that aids in is differentiation from mycosis fungoides is the monomorphic nature of the lesions and their synchronous distribution in time (Figure 1). [Mycosis fungoides in children and adolescents: a report of six cases with predominantly hypopigmentation, along with a literature review]. In that setting, the clinical and pathological features of PLC would be interpreted as a form of chronic graft-versus-host disease. Pityriasis lichenoides is the name given to an uncommon rash of unknown cause. Also, the treatment of children is slightly different from that of adults, with an emphasis on antibiotics. All rights reserved. Pityriasis lichenoides chronica, short form PLC, is the chronic version of the Pityriasis lichenoides et varioliformis acuta, also called Mucha Habermann's Disease.

However, to the best of our knowledge, no studies describing histopathological findings in these lesions are reported in literature. according to medscape, pityriasis lichenoides is "a rare cutaneous disorder of unknown etiology," characterized by "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 There are two types of pityriasis lichenoides: an acute (more sudden onset and less persistent) form known as pityriasis lichenoides et varioliformis acuta (PLEVA), and a milder, more persistent form known as pityriasis lichenoides chronica (PLC). J. Dermatol. The rare associations of pityriasis lichenoides with lymphomas are reviewed.) If you need help finding information about a disease, please Contact Us.

Typically, onset is at a young age, and severity waxes and wanes over time. Venereol. Pityriasis lichenoides chronica was diagnosed in 39 cases (76.47%) and pityriasis lichenoides et varioliformis acuta (PLEVA) in 12 cases (23.53%). On the initial visit, the differential diagnosis is explained to the patient, along with the need for biopsy diagnosis. These three forms represent a spectrum of disease presentation. Yes, Pityriasis lichenoides chronica is a skin disorder that normally resolves on its own, but treatment with medications may speed up the process. It is believed that genetically susceptible individuals mount an inappropriate immune response to a foreign agent, such as a virus or medication, which causes inflammation in the skin. Sometimes people mistake pityriasis lichenoides chronica for other diseases such as eczema or psoriasis, but pityriasis lichenoides chronica does not affect the whole body like eczema or psoriasis. In the setting of a transplant, we know the cause. Tanning parlors are often the modality of choice for patient convenience and expense. FOIA Because of the rare but possible transformation to malignancy, careful follow-up and repeated biopsies is advised in chronic intermittent disease. The clinical and pathological correlation typically suffice for the diagnosis. @article{Magro2007PityriasisLC, title={Pityriasis lichenoides chronica: stratification by molecular and phenotypic profile. J. Dermatol. This review provides a broad view of the clinical spectrum in the pediatric population. Lesions at various stages may be present at any one time.

Pityriasis lichenoides chronica (PLC) lesions are reported to subside with post-inflammatory hypopigmentation (PIH); hence, the most widely perceived nature of hypopigmented macules in PLC is PIH. They first appear pink and scaly, and they gradually flatten and become brown in color over a period of weeks or months.
