The Sydney Melanoma Diagnostic Centre


The Sydney Melanoma Diagnostic Centre (SMDC) was the conception of Professor Scott Menzies and Professor William McCarthy, both of whom had previously been working at the Sydney Melanoma Unit; Professor Menzies since 1991 and Professor McCarthy for over 18 years, 10 years as Director of the Unit. They had a wish to set up a new Unit that would focus on the earlier diagnosis of melanoma using state of the art technology (eg. computer digital monitoring, automated image analysis, total body photography and dermoscopy).  The Sydney Melanoma Diagnostic Centre (SMDC) opened in 2002 with Professor Menzies as its first Director and Professor William McCarthy as Deputy Director.  

Our vision is to use our clinical expertise and research leadership to develop and apply new imaging techniques for the accurate diagnosis and management of skin cancers and melanoma.

This vision has led us to train in physics and optics and has enabled us to understand and influence physicists/ industry in the early phase of developing innovative tools. It has also crystallized the focus of our dermatology practice on the diagnosis of melanoma and skin cancer. Furthermore, it has encouraged us to develop more national and international collaborations in order to enhance the skills and training of dermatologists to develop and use these techniques appropriately.
