Abstract
We describe the use of screen mirroring, as a modification of the previously described “selfie-stick examination” method for the examination of skin lesions on the back of the patient. This would be especially useful in the context of patient initiated tele-dermatology for lesions over the back.
Keywords: Back examination, melanoma, mole, selfie stick
Various methods have been suggested to enhance skin self-examination over areas that are difficult to visualize, like the back. One of the methods which has been used effectively is the “selfie-skin examination,” which involves the use of a selfie stick and a full-length mirror to assist self-examination.[1] However, manipulating the camera while simultaneously visualizing the reflected image on the mirror might be difficult. The use of screen mirroring has been described as an useful method to reduce infection exposure, in the context of the COVID-19 pandemic, for both clinical and dermoscopy imaging.[2] We combined the selfie stick examination with screen mirroring (using either a television or a PC) to visualize and capture images of lesions over the back. The selfie stick is used to focus the smartphone camera over the lesions over the back, while the same is mirrored real time onto a larger screen. The main camera is used to capture the images (because the main camera usually has a higher resolution when compared with the selfie camera) [Figures 1 and 2].

This method reduces the inconvenience of having to depend on a fixed mirror to monitor the reflections. The patient can also use the “print screen” option on the keyboard to take images as screenshots on the PC. Screen sharing using web-conferencing software can be combined with this procedure during live tele-consultations, and the dermatologists could ask the patient to focus on specific suspicious lesions. The main practical problem associated with this is the difficulty to focus the camera. In general, using the camera with the flash on (not automatic flash) tends to improve the quality of the images by reducing blur. The other limitation is use in older people, who may not be familiar with or comfortable with technology in general and selfie sticks in particular.
This method could improve the quality of images captured for patient-initiated teledermatology, especially in the context of the Covid-19 pandemic, as part of skin self-examination over areas which are difficult to visualize.
