Brief Summary
This clinical trial tests the addition of preferentially expressed antigen in melanoma (PRAME) immunohistochemical (IHC) staining to standard slow Mohs micrographic surgery (SMMS) for guiding tissue removal in patients with stage 0 to IIc cutaneous melanoma. SMMS is a method of skin cancer removal involving repeated tissue removal and examination under a microscope to ensure the tumor is removed as much as possible while sparing healthy tissue. In SMMS, tissue sections are evaluated to determine whether additional tissue removal is needed. The standard method for evaluating the tissue is by using a specific stain called hematoxylin and eosin (H\&E) stains. PRAME is a cancer antigen that is being investigated as a diagnostic marker in certain types of cancer. Adding PRAME IHC analysis to standard SMMS staining methods may improve the accuracy for determining whether additional tissue removal is necessary for patients undergoing SMMS for stage 0 to IIc cutaneous melanoma.
Eligibility Criteria
Inclusion Criteria: * Scheduled for SMMS of cutaneous melanoma (stage 0 through stage IIc per American Joint Committee on Cancer \[AJCC\] criteria) * Age \>= 18 years at time of consent * Initial tumor biopsy is PRAME positive or PRAME testing was not done. PRAME testing must be planned if not done * Provision of signed and dated informed consent form * Stated willingness to comply with all study procedures and availability for the duration of the study Exclusion Criteria: * Initial biopsy was PRAME negative * Incarcerated persons * Patient with severe, active co-morbidity that would preclude a SMMS of cutaneous melanoma (stage 0 through stage IIc per AJCC criteria)
