Hi Diane,
I am glad you can’t spell Dupuytrens either.
Every time I make this diagnosis I have to google the spelling !!!!
In my mind I think of these as the same entity.
Dupuytrens is indeed palmar fibromatosis so I think of dupuytrens as being palmar fibrosis.
It is different to post op granulation tissue but this would always be in the context of prior surgery or penetrating injury.
It is quite possible that I am being over simplistic about this and I would really value the opinion of Greg Lammers as he is particularly clever when it comes to hands and fingers.
I would have called your case Dupuytrens and the fact there is no flexion deformity is perfectly OK as this does not develop until the later stage of the disease.
Steve.
