Peyronie disease (Peyronies), also known as Morbus Peyronie or Induratio Penis Plastica (IPP), results in a bent penis due to collagen accumulation and tissue contraction. Possibly this is due to a genetic disposition. IPP can appear quickly while Dupuytren's contracture typically develops over 5 - 10 years. It also seems that self-healing, i.e. spontaneous healing without treatment, is more frequent for IPP than for Dupuytren or Ledderhose (though self-healing cases might possibly not have been Peyronies). About 15 - 20 percent of patients suffering from Peyronie's also suffer from Dupuytren's contracture  thus supporting the concept of a common or related root cause.
