Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The primary objective of Part Two is to test the sensitivity and specificity as well as feasibility of field use of an automated TBDP app to detect pigmented and non-pigmented skin lesions in high risk populations.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In order to assess whether or not the software will accurately detect spot changes, the investigators will test the product on a sample of volunteer subjects.
Part One:
The study population will undergo one study visit. This visit will include 2 sets of photos taken by the research team after the collection of a small amount of identifying and contact information for each subject. There will be an initial 3-5 photographs taken of areas of the body that have at least 3 natural or artificial skin markings (ie. moles, angiomas, scars, keloids, seborrheic keratosis, small tattoos, etc). These markings will allow the app to calculate the parameters of any original lesions, and thereby more accurately detect new markings or changes based on these calculations. Once the original photographs are taken, one of each individual's original skin marking will be enhanced/enlarged with a marking pen, as well as 3- 5 new marks added to the skin. A Sharpie brush tip permanent marker will be utilized to make the new skin markings. These markers have been AP certified to be non-toxic. The following colors have been chosen: orange, black, brown, red, blue, purple, yellow and pink. A second photograph will be taken of the same areas of the body chosen for initial photographs to determine if the application could detect the changes. This group will not have their images sent to a dermatologist for evaluation, as they are artificially produced.
Part Two:
In order to test the sensitivity and feasibility of field of use of the TBDP app, a second convenience sample of patients will be recruited. Recruitment will be done in waiting rooms with the attending physician's consent. If needed, recruitment will be done outside of the waiting room in the form of flyers, website and e-mail announcements. This population will consist of patients with known high risk to have new/changing lesions, and who fall within the Fitzpatrick skin types I-IV. High risk patients include, but are not limited to, those with dysplastic nevus syndrome, previous history of melanoma/non-melanoma skin cancer, fair skin, \>16 nevi, family history of melanoma, and/or immunosuppressed status. The first photography session will be taken by the research team in all 13 projections. Each projection corresponds to each body area that will be photographed to ensure total body photography. After the first visit, the patient will be instructed to take photographs every month for 12 months using the TBDP app on their smart phone or tablet, and have follow-up research appointments every 6 months. The patient will be provided a user guide with written instructions for application use. The TBDP app has a built-in reminder system for the patient. Any changes detected by the app will be stored on the research team's database. Standard of care will be followed for any new/changing lesions. Patients will be recommended to have a follow-up appointment with their dermatologist, within 2 weeks. No procedures will be completed by the research team, and a physician will not be seeing the patients during their research appointments. During these visits, the research team will compare the photographs taken by the TBDP app to the patient's skin to see how sensitive the app is. Patients will continue their regular office visits at 6 months and/or 12 months as per standard of care for high risk patients. The research team will use information from chart reviews for assessment of the outcome for new or changing lesions.
