A link between Dupuytren's and Peyronie's may or may not exist https://www.dupuytren-online.info/IPP_and_others.html . A patient survey by the International Dupuytren Society in 2015 https://www.dupuytren-online.info/patient_survey.html did not show any conncection, different to Ledderhose which seems to be well connected with Dupuytren's.

I am sorry but I don't find those two papers convincing. The first one has a very small sample of just 9 patients, which makes it statistically irrelevant. The second one already presumes a connection between both diseases ("Peyronie's disease (PD) is known to be associated with Dupuytren's disease (DD) since 1828.") and finds that 22% of the patients with PD are also suffering from DD. Depending on the age distribution this might just be "normal" and not excessively much. E.g. in The Netherlands, the overall prevalence of Dupuytren's is 22 % https://pubmed.ncbi.nlm.nih.gov/23897337...to%2080%20years .

In the patient survey, as presented at the Groningen conference in 2015, more than 2,000 patients with DD participated. 9.5 % of the patients with DD also suffered from PD. The survey used the reported Age of Onset (AO) as figure of merit and found that having also PD did not make any difference in the age of onset of DD.
Without PD AO = 44.9 with PD AO = 46.5
That's quite different e.g. to Ledderhose (LD) which seems to be strongly connected with DD
Without LD AO = 49.2 with LD AO = 43.9

That means that patients suffering from both, DD and LD, experience a much earlier onset of Dupuytren's while suffering also from PD doesn't seem to make any difference. From this I would suspect that the link between DD and PD, if there is any, is only a weak one.

A quick search suggests that it is more than just a possible statistical link but a causal link too. If we characterise these conditions as variants of an underlying fibrosis disorder then you would expect it to manifest in different ways. First two papers in my search were https://www.auajournals.org/doi/abs/10.1...%2817%2952751-2 and https://www.nature.com/articles/ijir201118 so there may be others. The DRG has a paper that confirms a common genetic base https://dupuytrens.org/similar-genes-fou...-and-peyronies/ But none of these answer the question will an individual with one manifestation also experience it in another way.

Wolfgang,

Do you have a link for the study showing that 9.5% of people with DD had PD from Groningen? I would be interested in reading more about that.
