SummaryThe diagnoses of 1,000 personal cases in a private dermatological specialist practice in South Australia over six months are recorded and analysed. Skin aging and malignancy accounted for 26.3%, constitutional eczema for 12.6 %, infections 11.4%, psoriasis 11.3% and adverse effects from chemicals and drugs, used either externally or internally, 9.8%. Clinical data is readily recorded in dermatological practice and clinical epidemiology could be valuable in assessing what steps in preventive medicine might be taken.
