Here are some statistics about
PRP.
The chance of getting PRP is about
1 in 400,000 (Clinical
Dermatology, By Richard Weller, John A. A. Hunter, John Savin, Mark Dahl).
That is about one person in a population the size of Malta.
There are different types of
PRP;
- About 50% of those with PRP have
Classical adult onset
- About 5% of those with PRP have
Atypical adult onset
- About 10% of those with PRP have
Classical juvenile onset
- About 25% of those with PRP have
Circumscribed juvenile
- About 5% of those with PRP have
Atypical juvenile onset
- And there is also a
HIV-associated variant
This table represents this split, with each square representing 5%:
The only types I could have are
Classical adult onset or Atypical adult onset, so I think my chances of having
Classical adult onset are 90.91% (10 out of 11) while my chances of having
Atypical adult onset are about 9.09% (1 out of 11)
For those with Classical adult
onset, 80% will have spontaneous remission within 3 years
For those with Atypical adult
onset, the condition may persist for 20 years or more.
