Summary

The article describes a common exanthematic disease typical of adolescence, pityriasis rosea Gibert. The significance of the name of the disease is explained and the historical implications of the origin of the name of the disease are clarified. The current view of its probable viral etiopathogenesis and its similarity to another exanthematous skin disease, exanthema subitum, are described. The prodromal stage of the disease and the clinical picture of the skin findings with characteristic seeding of lesions resembling „Christmas tree branches“ are described. The author‘s clinical pictures of the findings in individual patients with this disease are included. The possible relationship with COVID 19 is noted. The differential diagnosis is discussed, including the similarity to secondary syphilis, and the uncharacteristic histopathological picture of the disease is described. Finally, treatment options are discussed, with the caveat that the very common use of topical corticosteroids is not very effective and rather non-corticoid external therapy is recommended.
