Oğrum A. Unilateral pityriasis rosea in a child: A rare clinical presentation. Turk J Pediatr 2017; 59: 214-216. Pityriasis rosea is a common papulosquamous disorder with occasional variations in lesion morphology, distribution, number and course of disease. The lesions are classically arranged with their long axes parallel to the Langer`s lines of cleavage and typically affect the trunk and the proximal extremities. Variations in the distribution of pityriasis rosea include inversus, localized, and unilateral forms. The unilateral form is a very rare variant of pityriasis rosea, particularly in children. We report a 15-year-old boy with pityriasis rosea demonstrating unilateral localization.

Beyond the Herald Patch: Exploring the Complex Landscape of Pityriasis Rosea.

Pityriasis rosea (PR) is a prevalent dermatological condition characterized by a distinctive herald patch, followed by secondary eruptions, often forming a "Christmas tree" pattern on the trunk. Despite its recognizable clinical presentation, the etiology of PR remains uncertain, with hypotheses pointing to both infectious and noninfectious origins. Human herpesviruses (HHV) 6 and 7 have been implicated, with evidence suggesting viral reactivation as a potential trigger.

Background: Psoriasis (PS), vitiligo (VT), and (PR) are chronic skin diseases often occurring as a consequence of exaggerated immune responses. These skin manifestations can be triggered as a result of the molecular mimicry between viral protein (s) and host protein (s), which could generate auto-antibodies. In addition, it can be hypothesised that skin diseases are manifestations of the reduced immunity that is observed in chronic hepatitis B virus (HBV)-infected individuals.

Article Synopsis
- Pityriasis rosea (PR) is a skin condition that usually gets better on its own, often linked to reactivated human herpesviruses, causing mild rashes and itchiness.
- Traditional treatment focuses on reassuring patients to rest, but severe cases may require medication, prompting a study comparing various treatments.
- The analysis found that oral steroids and a combo with antihistamines were effective for itch relief, while acyclovir was the most effective for improving rash symptoms, making it the best option for more serious PR cases.
