Summary
Brief summary (as posted)
This study will evaluate whether digital photography is a reliable tool for diagnosing hand rashes, psoriasis and unusual moles. The findings will help determine if this method can be used in the National Health and Nutrition Examination survey (NHANES), which monitors disease in the United States. Employees of the National Institutes of Health 19 years and older may enroll in this study. Participants will complete a brief questionnaire that includes information on skin type, history of skin conditions (moles, cancer, rashes, psoriasis), and demographic information such as name, age and sex. They will be examined by a dermatologist, who will note in writing the appearance of any hand rashes, unusual moles, or psoriasis. If any areas suspicious for skin cancer are found, the participant will receive this information in writing, along with advice about where to go for treatment. A total of six photographs will then be taken of the participant's arms, legs, hands and back. The face will not be photographed, and the participants will not be identifiable.

Must have employee status at the National Institutes of Health. Age greater than 18 years. Able to understand and sign consent. Patients who are wheelchair bound and are unable to have images of their back and lower extremities taken safely will be excluded from photography since this portion of the examination requires an ability to stand. However, they will still be eligible to participate in the skin cancer screening.
