It's a German language textbook, for which Kenny Mattonet, Jörg Wilting and myself wrote the chapter about the genetic causes of primary lymphedema. Get it from here, since Amazon still sells the old edition. If you have a really good excuse why you should get one for free, please mail me (firstname.lastname@example.org)! I have a few copies.
The 6th edition of the book Erkrankungen des Lymphgefäßsystems (Diseases of the Lymphatic System) is out.
