Hi. Thanks for posting your concern. Classic Pityriasis rosea presents with scaly oval patches (scale is adherent at the periphery and loose in the center) oriented along the ribs and forming a christmus tree pattern. The generalised rash is preceded by single or two mother patches (herald patch) and thereafter a generalised crop of lesion appears on the trunk and proximal extremities. There can be recurrent crops of new lesions while the old ones resolve. I usually treat my patients of pityriasis rosea with a topical moderately potent steroid like mometasone twice daily for 2-4 weeks. Some dermatologists also prescribe oral erythromycin 250mg thrice daily for 2-4 weeks for widespread eruptions. An oral antihistamine once daily e.g cetrizine takes control of the itch take care regards
