10 Pityriasis Rosea Facts
Pityriasis rosea is a type of skin rash that was first described in 1860. The name translates as “fine pink scale.” It is a condition commonly seen among young adults and children.
Other skin eruptions that are similar include psoriasis, pityriasis rubra pilaris, and lichen planus. This condition usually occurs abruptly. However, it is usually self-limiting where patients present with a rash of 6 to 8 weeks.
It is a very common condition among the general population. In the United States, most cases are seen during spring and winter with estimates of about 0.13 percent in females and 0.14 percent in males. Globally, this condition accounts for approximately 2 percent of dermatologic outpatient visits. In countries like India, Australia, and Malaysia, pityriasis rosea is more likely seen during the hot and dry seasons.
