Dermoscopy Imaging in Teledermatology

  • With dermoscopy, things get simpler, fortunately. Dermoscopy is so important for us to make a diagnosis, especially for those of us that work in oncology.
  • Sometimes even when the clinical image is bad, we can make a diagnosis because we do get a good dermoscopic image.
  • As an anecdote by the presenter: “I always tell them as a joke that you need to take a course to take a good clinical picture, but you need to take a course to take a bad dermoscopic image.
  • Indeed everything is set to capture the image: the distance is the same, the lighting is the same, the colors are preserved…the most common mistake then with dermoscopy is to take pictures with the crust: it needs to be removed so that you can see what’s below the crust.
  • Also, when the lesion is big, it’s important to have a closeup image and then one farther away. Nowadays, basically all dermatoscopes include a scale.
  • Please also refer to the articles imaging in dermoscopy of inflammatory lesions (Dr Tejasvi) and pigmented lesions.
