A mild irritating rash affecting young people, which appears especially in the early part of the year and has no known cause.
A benign (noncancerous) skin rash that usually begins with a single oval patch and then spreads. The original patch, which may be rosy pink, salmon, or tan, commonly appears on the trunk. Within a week or two after the emergence of the first patch, smaller, similar plaques (patches of thick, raised skin) appear more generally over the trunk. Pityriasis rosea is most common in children and young adults and affects both sexes equally. It usually disappears on its own without treatment and leaves no permanent marks. Treatment with ultraviolet B light, antihistamines, and hydrocortisone cream may be prescribed to relieve itching.
An acute inflammatory skin disease of unknown etiology, marked by a macular eruption on the trunk, obliquely to the ribs, and on the upper extremities. The initial (herald) patch appears in more than half of the cases. In a few days it enlarges to several centimeters. Then, within 2 to 21 days, secondary eruptions occur. They are rosered and somewhat scaly with a clearing in the center, or reddish ring-shaped patches symmetrically distributed over the limbs. The symptoms disappear spontaneously within 2 to 10 weeks. Treatment consists of the local application of antipruritics.
An ordinary and mild skin ailment characterized by the emergence of a rash consisting of pink spots or patches with flat and scaly edges. This rash typically occurs on the upper arms and trunk. It’s important to note that this condition is non-contagious and primarily impacts children and young adults. While its exact cause remains uncertain, there’s a possibility of it being linked to a viral infection.
The initial indication is the presence of a sizable, circular mark known as a herald patch, situated on the trunk. Roughly a week later, the rash becomes visible. This rash persists for a duration of four to eight weeks, potentially inducing itching, yet typically fades away on its own without requiring treatment. To alleviate any itching, individuals can consider using calamine lotion or antihistamine medications.
A skin condition affecting the torso, marked by light red patches with tan centers. Its cause remains unidentified. Typically, it resolves on its own within three to six weeks, whether treated or not. It’s also referred to as pityriasis circinata or herpes tonsurans maculosus.
