This research study will determine how a smart phone application (app) for total body photography outlier analysis compares to a dermatologist's decision to biopsy skin lesions.

Informed written consent will be obtained by all study subjects. Each participant will be asked to generate a unique identifier, so their demographic data, medical intake, and study assessments can be stored without any patient identifiers. The unique identifier is the participant's 2-digit day of birth, first 3 initials of their mother's maiden name, and the 4 digits of their birth year. All clinical data will be entered into a de- identified database.

Demographic information including age, gender, ethnicity, collected via medical intake survey at the initial visit. Data from the survey will be associated only with the patient's unique identifiers.

Inclusion Criteria:

• Males and females participants in overall good health ages 18 to 85 who have skin lesions

Exclusion Criteria:

• Those who are under 18 or over 85

Males and females participants in overall good health ages 18 to 85 who have skin lesions
