Pityriasis lichenoides et varioliformis
acuta is a disease of the immune system. It is the more severe version of
pityriasis lichenoides chronica. The disease is characterized by rashes and
small lesions on the skin. The disease is more common in males and usually
occurs in young adulthood, although it has been seen in every age group and
every race. It is possible for the disease to go into remission for short
periods of time or forever. Diagnosis
It is commonly misdiagnosed as chickenpox or rosacea. Pleva is also
often misidentified as a form of staph. The most accurate way to diagnose it is
by biopsy. This disease has not been known to be life-threatening. However,
there may be mutations of the disease that can cause ulcers on the exterior.
Causes There is no known cause of this disease;
There is some evidence associating it with Parvovirus B19.
Treatment It is not contagious and currently there
is no cure for the disease, although the lesions can be treated with ultraviolet
therapy as well as topical steroids and antibiotics.
Treatment often involves multiple therapies that address the immune system
and bacterial, viral, or dermatological causes.
Eponym It is named for Rudolf Habermann, a
German dermatologist, and Viktor Mucha, an Austrian dermatologist.
