The teaching material includes a collection of 137 dermatological casts, the vast majority of which were made by the doctor Adolphe De Leeuw before 1937 (when the museum of casts opened).

​

Alongside these wax casts are a number of anatomical drawings signed by practitioners such as Dr Marc Roussiel, a surgeon at the Hôpital Saint-Jean and then the Hôpital Brugmann in the early 20th century.

​

Finally, the collection includes photographs of medical procedures, X-rays and numerous glass plates.
