ATYPICAL PITYRIASIS ROSEA: A REVIEW OF THE LITERATURE
Journal Title: European Journal of Pharmaceutical and Medical Research - Year 2019, Vol 6, Issue 5
Abstract
Pityriasis rosea (PR) is a common, self-limiting skin condition mainly seen in teenagers and young adults. It is characterized by the distinctive ‘Herald Patch’ or ‘Mother Patch’ followed by secondary smaller lesions. Reactivation of HHV6 and HHV 7 have been most suggested as causative agents. For most dermatologists, making a clear diagnosis of PR maybe a piece of cake. However, the challenge lies in not identifying what is most common but in the more atypical manifestations of this cutaneous eruption. The differential diagnoses for each and every type is exhausting and so a lesional biopsy can help to rule out most of them, if applicable. Since this disorder generally resolves in 2- 12 weeks, counselling of the patient is advised. Emollients and moisturizers can be used to alleviate pruritus. Acyclovir is the most effective treatment option, being effective as early as in the first week itself. Topical corticosteroids are to be used sparingly for severe pruritus only. By proper identification of the various forms of this papulosquamous disorder, patients can be treated properly without any misdiagnosis and unnecessary treatment interventions. This article is to review the current and critical information on pityriasis rosea and its atypical manifestations.
