[The Rostock moulage collection].

Wax moulages are valuable witnesses of the beginning of dermatology as an independent speciality. In addition, they document changes in the allocation of clinical pictures to certain conditions. This has been due to the knowledge about new etiologies of dermatologic disorders, which have been steadily increasing since the beginning of the 20th Century. Furthermore changes in the frequency of certain diseases can be recognized to some extent. The still existing moulages of the Department of Dermatology and Venereology of Rostock offer some interesting examples.
