Brief Summary:
This study is designed to collect information about melanoma using a research probe, a device placed only on the skin. This study will investigate whether using the probe to examine skin lesions could improve the accuracy of identification pre-cancerous melanoma lesions or to predict the risk melanoma in the skin of subjects. Ultimately, we would see this technique used routinely as a non-invasive device during subjects' skin examination to aid dermatologists to identify pre-cancerous (melanoma) lesions without taking tissue samples of the skin. Alternatively, this technique would, in the future, also be used to screen patients at risk for melanoma.

Primary Outcome Measures :
  1. Investigate the ability of the fiber-optic probe to identify lesions of melanoma and severe/high-grade dysplasia [ Time Frame: 3 years ]
    To correct for skin color effect and heterogeneity, the readings of the pigmented lesion will be normalized by the readings taken from the corresponding normal skin around the lesion.

Secondary Outcome Measures :
  1. To test whether the fiber-optic probe can discriminate the severe/high-grade dysplasia from the mild and moderate dysplastic nevi; [ Time Frame: 3 years ]
  2. To test whether the fiber-optic probe readings are different among tissues with different degree of sun exposure [ Time Frame: 3 years ]
  3. To test whether the fiber-optic probe readings are different between the most and the least suspicious lesions [ Time Frame: 3 years ]

Biospecimen Retention:   Samples With DNA

A pigmented lesion is removed as part of the subjects routine care when it is felt to be suspicious for severe atypica or early malignancy, and sometimes because the patient desires removal of lesions for cosmetic reasons, or because the lesion is irritated or located in a zone of traum.

For this research study, samples of the tumor tissue from these clinical care biopsies will be studied.

Researchers will look at markers and search for additional characteristics that may help them better understand Melanoma. This will be optional to subjects. If subjects do not agree to have their tissue kept for future research purposes they can still participate in the rest of this study.
