The MelaFind® melanoma detection system was developed by Mela Sciences a clinical dermatology company.1 The system is used to help evaluate suspicious skin abnormalities (lesions). Specifically, the test is used to determine whether a particular colored (pigmented) skin lesionThis is a broadly used term in pathology and refers to any defined (localized) structural abnormality or injury. The word 'lesion' does not imply that something (i.e. a tumor) is necessarily serious or advanced. is likely to be melanoma. MelaFind® uses a sophisticated imaging system to capture photographs of the skin abnormality. The photograph is then compared to a database created from 10,000 skin biopsies. The result is a simple 'yes' or 'no'. The result can be used to help guide biopsyA medical procedure in which a sample of tissue is removed for examination. Biopsies can range from a small sample drawn into a needle to samples taken during more invasive surgery. decisions. In clinical trials, MelaFind® was found to be very sensitive in detecting melanoma.2 The test was approved by the FDA in November 2011.3
MelaFind® is not used on all skin lesions or all part of the body. According to the manufacturer's website, MelaFind® is effective at finding melanomas ranging in size from 0.2 cm to 2.2 cm (2.54 cm = 1 inch). Larger or smaller lesions are not readily imaged by the system's cameras.
