Intervention

Device:
• Epicutaneous cryoimmunotherapy
Epicutaneous cryoimmunotherapy (EC) treatment includes liquid nitrogen cryotherapy applied for 10 seconds x 2 freeze-thaw cycles. Four treatment areas will be chosen at each treatment.

Drug:
• Topical imiquimod
Patients will apply the cream directly over the treatment areas and can use up to one packet per day (covers approximately 5 cm x 5 cm).
• Pembrolizumab
Pembrolizumab 200 mg will be administered as a 30 minute IV infusion

Other:
• Dermatologic Quality of Life Index
10 questions about how much skin problems has affected the participant's life over the past week The scoring of each question is as follows: very much = 3, a lot = 2, a little = 1, not at all = 0, not relevant = 0, and question #7 'prevented work or studying' = 3 The DLQI is calculated by summing the score of each question resulting in a max of 30 and min of 0. The higher the score, the more quality of life is impaired.
• Functional Assessment of Cancer Therapy
5 subscales (physical well-being, social/family well-being, emotional well-being, functional well-being, and additional concerns) Answers ranging from 0=Not at all to 4 = very much Each item is rated on a 5-point Likert scale. The higher the score on the social/family well-being and functional well-being indicate higher quality of life The lower the score on physical well-being, emotional well-being, and additional concerns indicate higher quality of life

Drug:
• Intra-lesional GM-CSF
250 mcg every 2 weeks x 3 doses then every 3 weeks for 3 doses

Device:
• Cry-AC
-Device used to give the cryoimmunotherapy

Procedure:
• Cutaneous tumor biopsy
-Baseline, week 3 (prior to 1st dose of pembrolizumab), week 9, and at week 18. An optional biopsy can be obtained at the time of disease progression.
• Peripheral blood draw for research
-Baseline, week 3 (prior to 1st dose of pembrolizumab), week 9, and at week 18. An optional biopsy can be obtained at the time of disease progression.

Primary	Safety and tolerability as measured by rate of treatment emergent grade 3 or higher toxicities	-NCI Common terminology criteria for adverse events (CTCAE v5.0) will be used to grade toxicities	From beginning of treatment through 90 days following completion of treatment or 30 days following completion of treatment if the participant initiates new therapy (whichever is earlier)
Secondary	Objective response rate (ORR) as measured by RECIST 1.1	For patients who present with discrete measurable lesions; ORR = number of patients who achieve CR or PR divided by the total number response-evaluable patients; Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.; Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.	Baseline and 18 weeks
Secondary	Progression-free survival (PFS)	Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions).; PFS is defined from date on treatment to the earliest date of progression, death, or last follow-up and progression or death are events of interest for PFS.	2 years
