Editor’s Note: The long-term prognosis for PRP is not set in stone. There are some guidelines that dermatologists feel comfortable in treating as Gospel.
Suffice it to say that there has been insufficient research to be able to predict when Type 1, 3 and 5 will “run it’s course.”
Adult Onset PRP
Type 1 — Classical Adult Onset PRP: Good prognosis with 80% of patients going into spontaneous remission within 3 years. After remission, relapses are uncommon
Type 2 — Atypical Adult Onset PRP: May persist for 20 years or more
Juvenile Onset PRP
Type 3 — Classical Juvenile Onset PRP: Spontaneous remission within 1 year
Type 4 — Circumscribed Juvenile Onset PRP: Long term outcome unclear but possible improvement in late teens
Type 5 — Atypical Juvenile: very persistent
Other Onset PRP
Type 6 — HIV-Associated PRP: Disease tends to be resistant to standard therapies. No further timeframe is suggested.
