Unit 0: Introduction
Dr Tony Dicker, an experienced skin cancer doctor and Associate Professor at the University of Queensland, introduces the dermatoscope as the clinician’s key diagnostic tool—comparable to a stethoscope in importance for skin examination. The course is designed for medical students, nurse practitioners, and primary care professionals new to dermoscopy, focusing on how to use the instrument rather than diagnosing specific conditions.
Unit 1: What is a Dermatoscope?
This unit defines what a dermatoscope is and how it differs from simple magnification. It explains how polarised and non-polarised light allow clinicians to visualise subsurface structures such as pigment, vessels, and skin patterns invisible to the naked eye. Participants learn about colour interpretation (brown, black, blue-grey, red, and purple tones), pattern recognition, and the role of polarising filters. The session also covers the evolution of dermatoscopes from large microscopes to today’s portable, high-resolution handheld devices.
Unit 2: How to Use a Dermatoscope
This practical unit demonstrates how to operate various dermatoscopes—turning on the device, adjusting brightness, warmth, and polarisation, and focusing for optimal clarity. Dr Dicker demonstrates techniques for applying liquid interfaces and using different lens attachments for challenging locations such as raised lesions, hairy areas, and spaces between toes. Participants learn safe hygiene practices, including cleaning the skin and lens with alcohol wipes and using ultrasound gel to improve image clarity.
Unit 3: Photography through a Dermatoscope
Here, learners explore methods for capturing and sharing dermatoscopic images. The session compares attachment systems—magnetic clips, locking mounts, and SLR-specific lenses—and teaches how to align focus points for clear, reproducible photos. Dr Dicker emphasises obtaining both overview and close-up images to preserve context and medico-legal accuracy. Participants also gain tips for managing light, avoiding reflections and air bubbles, and maintaining focus when photographing lesions.
Unit 4: Storing Images
This unit focuses on secure, compliant storage of dermatoscopic and clinical images. Options include uploading photos to electronic medical records, maintaining structured local files, or using dedicated systems such as PhotoFinder. Dr Dicker highlights the importance of consistent file naming, long-term data management planning, and meeting medico-legal obligations. Practical advice includes separating clinic and personal devices, using old phones as dedicated clinic cameras, and preventing data breaches under Australian privacy law.
Unit 5: Care and Maintenance
The final unit outlines how to clean, care for, and maintain a dermatoscope to extend its lifespan. Topics include safe cleaning with 70% alcohol wipes, avoiding abrasive cloths or autoclaving, removing gel residue, and using microfibre cloths to protect the glass plate. Battery care is covered, with tips on recharging, replacement cycles, and preventing internal damage. Participants finish with clear steps to ensure their dermatoscope remains in reliable working condition.
