What does it mean when your face is red with pus?
The exact cause of pityriasis rosea is unclear. Some evidence indicates the rash may be triggered by a viral infection, particularly by certain strains of the herpes virus. But it’s not related to the herpes virus that causes cold sores. Pityriasis rosea isn’t believed to be contagious.
It also is not due to any known type of allergic reaction. This condition is not a sign of any type of internal disease. Since it is neither contagious nor sexually transmitted, there is no reason to avoid close or intimate contact when one has this eruption.
Its exact cause is unknown. No germ (bacterium, virus, or fungus) has been found in people with the rash. However, certain types of human herpes viruses may be a part of the cause. It is not associated with food, medicines or stress.
It may be caused by many things, including insect bites, allergic reactions, medication side effects, fungal skin infection, bacterial skin infection, infectious disease, or autoimmune disease.
In most cases, pityriasis rosea is harmless and doesn’t return after it goes away. If your case lasts longer than 3 months, check in with your doctor. You may have another condition or be reacting to a medication.
Who is most at risk for getting pityriasis rosea? Anyone can get pityriasis rosea. However, the condition appears most often in people between the ages of 10 and 35.

In an uncommon type of pityriasis rosea, the rash may be concentrated in the armpits and groin or on the face, forearms, and shins. Pityriasis rosea usually begins with a single patch of pink-to-red, scaly skin, from 2–5 cm in size. This “herald patch” is usually located on the trunk, neck, or upper arms.
During the progression of leukemia, white blood cells (neoplastic leukocytes) found in bone marrow may begin to filter into the layers of the skin, resulting in lesions. “It looks like red-brown to purple firm bumps or nodules and represents the leukemia cells depositing in the skin,” Forrestel says.
Several autoimmune skin diseases are responsible for causing skin blistering, including:
