Response: This systematic review was one of a series of Cochrane Reviews of studies evaluating different tests for diagnosing skin cancer. Within creasing rates of skin cancer and an increasing number of more specialised tests becoming available in both primary care and in specialist settings, a thorough review of all available evidence was timely.
The diagnosis of melanoma and other skin cancers fundamentally relies on clinical examination, including history taking, and visual inspection of the concerning skin lesion (mole or patch of skin) and surrounding skin (and other lesions). A dermatoscope is a handheld device using visible light (such as from incandescent or LED bulbs), that allows more detailed examination of the skin compared to examination by the naked eye alone.
Knowing the diagnostic accuracy of dermoscopy added to visual inspection alone, across a range of observers and settings, is critical to understanding its contribution for the diagnosis of melanoma and to future understanding of the potential role of the growing number of other high-resolution image analysis techniques.(more…)
