A novel infrared imaging tool to aid in the clinical detection of atypical pigmented lesions and melanoma is developed. Goals include evaluation of the utility of high-resolution infrared scanning of cutaneous lesions in the diagnosis of pigmented lesions and the identification of high-risk lesions and melanomas.

This study uses a specific skin protocol to cool the skin and then measures the cutaneous thermal recovery to uniquely identify lesions that may be cancerous. Using computer models, the thermal signature is used to determine the size and shape of the lesions in question. In particular, this study seeks to add quantification analysis of high resolution thermal images of melanoma lesions to provide accurate early diagnostic capability with specific detail regarding size, shape and depth of the lesions. This information will be compared to biopsy results and surgical resection results.

Inclusion Criteria:

• Patients seen in the high-risk pigmented lesion clinic, who posses a pigmented lesion with a clinical indication for biopsy

Exclusion Criteria:

• None

The subject population will be identified in the Department of Dermatology Pigmented Lesion Clinic at the Johns Hopkins Hospital Outpatient Center. Recruited patients will only comprise those requesting a cutaneous pigmented lesion removed or patients that are examined and found to have a pigmented lesion that is suspicious for malignancy at the time of their visit, and thus recommended to have a skin biopsy for diagnosis following the standard of care
