Pityriasis Rosea

Definition 1

A mild, self-limited skin disorder that is most commonly seen in children and young adults. It is characterized by an initial large round spot on the chest, abdomen, or back, often referred to as a herald patch, that is usually followed within a week by a distinctive pattern of similar but smaller papules on the torso, arms, and legs. There may also be itching, especially when overheated. (NCI Thesaurus)

Definition 2

A mild exanthematous inflammation of unknown etiology. It is characterized by the presence of salmon-colored maculopapular lesions. The most striking feature is the arrangement of the lesions such that the long axis is parallel to the lines of cleavage. The eruptions are usually generalized, affecting chiefly the trunk, and the course is often self-limiting. (NLM, Medical Subject Headings)
