چکیده
Pityriasis rosea is a short-lived rash that commences initially as a large so-called ‘herald’ patch followed by a rapidly evolving eruption on the trunk and extremities. Characteristic pattern of lesions follow the lines of cleavage in a ‘christmas tree’ distribution. PR is most frequently seen between first and third decade but a range of 3 month to 83 years were reported. The incidence doesn’t change according to sex (1,2). Clinical types of PR are papular PR, vesicular PR, pustular PR, inverse PR, cephalic PR, PR gigantea, PR urticata, and purpuric PR(1). The typical presentation of PR is easily recognized. The condition was first reported by Gibert in 1860. Hartman first described a patient with purpuric PR in 1994 (1,2). Up to now, there have been only 11 case reports related to purpuric PR in the literature (1,2). Therefore, we aimed to present such an interesting and rare variant of PR.
