  Purpose

This study is divided into distinct sample collection and analysis phases. In the sample collection phase investigators will tape strip lesions that are designated for biopsy because they are suspected for melanoma. No biopsies will be taken solely in support of this study; rather patients that present lesions that are to be biopsied—in the context of the standard of care—will be enrolled in the study and will have that lesion(s) tape stripped before the biopsy procedure.

In the second phase of the study, tape strip samples will be extracted and RNA purified and expression profiled by DNA microarray. The gene expression data will be correlated with histopathology with the expectation that an expression classifier that distinguishes suspect lesions from melanoma can be defined. That classifier will be validated in future studies.

Arms Assigned Interventions
A
This research study proposes to use a non-invasive method to capture superficial cells on pigmented skin lesions that are suspected of being early melanomas. This non-invasive "biopsy" technology has been developed and patented by DermTech International. RNA in skin cells captured by this method will be profiled in order to diagnose the nature of the lesion (i.e. malignant melanoma or not). A successful outcome of this proposal would create a candidate non-invasive diagnostic assay based on a gene expression profile for identifying early stage melanomas
Other: EGIR Tape
Tape stripping is a non-invasive method that allows the recovery of cells
Other Name: Tape stripping (EGIR™)
