- Histological diagnosis of melanoma, unresectable stages III-IV with accessible cutaneous, subcutaneous, and/or nodal lesions , according to the AJCC Staging Manual, 7th Edition, 2011.

Note: Patients who are considered to have resectable disease but decline resection are eligible.

• At least one lesion > 0.5 cm and < 2 cm
• ECOG performance status 0, 1 or 2
• Negative pregnancy test for women of childbearing potential within 7 days of enrollment on study.
• WBC > 2,000/mm3; ANC > 1,000/mm3; platelet > 100,000/mm3;hemoglobin > 9 gm/dL (may be transfused)
• Serum bilirubin levels <1.5 mg/dL except for patients with Gilbert's syndrome.
• Serum aspartate transaminase (AST) and serum alanine transaminase (ALT) < 2.5 X upper limit of normal, alkaline phosphatase < 2.5 X upper limit of normal.
• Serum creatinine levels <1.5 mg/dL
• Women of childbearing potential should be advised to avoid becoming pregnant and men should be advised to not father a child while receiving treatment with ipilimumab or interleukin-2. Patients should agree to use an appropriate method of birth control while on study. Examples of adequate forms of birth control for women include oral or implanted contraceptives, intrauterine device (IUD), diaphragm with spermicide, cervical cap, abstinence, use of a condom by the sexual partner or sterile sexual partner and also based on the judgment of the investigator.

• History of any other malignancy requiring active treatment
• Pre-existing autoimmunity: History of inflammatory bowel disease; history of symptomatic autoimmune disease (e.g., rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, autoimmune vasculitis [e.g., Wegener's Granulomatosis]); motor neuropathy considered of autoimmune origin (e.g., Guillain-Barre Syndrome). History of vitiligo is allowed.
• Chronic use immunosuppressants or systemic corticosteroids. Note: Chronic use is defined as requiring corticosteroids for greater than one month prior to enrollment on study. Corticosteroid use for less than 1 month prior to enrollment is allowed, but use must stop prior to starting study treatment.
• Clinically significant cardiovascular disease (e.g., uncontrolled hypertension [BP >150/100], myocardial infarction or stroke within 6 months, unstable angina), New York Heart Association (NYHA) Grade II or greater congestive heart failure, or serious cardiac arrhythmia requiring medication
• Currently active systemic infection
• Known history of HIV infection or chronic hepatitis B or C.
• The presence of any other medical or psychiatric disorder that, in the opinion of the treating physician, would contraindicate the use of the drugs in this protocol or place the subject at undue risk for treatment complications
• Pregnancy or breast feeding

• Any reason why, in the opinion of the investigator, the patient should not participate
