Unusual combination of clinical forms in a young man

Abstract

Uncommon forms of pityriasis rosea (PR) are found in a not inconsiderable proportion of patients (totaling approximately 20%) and predominantly affect children and young adults. They are characterized by atypical morphology and distribution of the primary medallion or also of the subsequent exanthematous individual lesions. The etiology of PR is not yet known. It is possible that the underlying cause of PR is viral in origin.
