Pityriasis rosea
Template:Infobox - disease Pityriasis rosea Gibert is an exanthematous disease typical for adolescence.
Epidemiology and etiology[edit | edit source]
It probably occurs in response to some viral infections (most likely HHV-7).[1] The disease is transient, maximum incidence is observed in spring and autumn. It most often occurs in people between 10 and 35 years of age.
Clinical symptoms[edit | edit source]
The disease is preceded by a prodromal stage, characterized by fatigue, subfebrile state, headaches and muscle aches, nasopharyngitis.
Then a so-called primary plaque (also called maternal deposit or plaque primitive)is formed – an oval erythematosquamous lesion of a 2-5 cm diamater, most often on the torso, shoulders or neck.
Within 1-2 weeks, similar but smaller foci typically form in the cleavage lines of the skin, especially on the trunk and proximally on the limbs (in the embolization location). Coleryette pityriaziform peeling of deposits is also typical. The rash can itch and is prone to irritation with frequent washing. Skin manifestations resolve spontaneously within a few weeks to months without sequelae.[1]
Differential diagnosis[edit | edit source]
Includes secondary stage syphilis, drug rashes, tinea, seborrhoeic dermatitis.
Therapy[edit | edit source]
It is not necessary, symptomatic therapy will suffice. Limitation of irritating effects, sometimes liquid powder is administered.
