* Patients who are receiving any other investigational agents
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to nivolumab
* Prior allogeneic transplantation
* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
* Any condition requiring \> 10 mg/d prednisone equivalents
* Current or prior HTLV-1 associated inflammatory diseases, including but not limited to myelopathy, uveitis, arthropathy, pneumonitis, or a Sjogren's disease-like disorder

* Grade 2 or greater toxicity from prior therapy
* Grade 2 or greater diarrhea
* Patients with active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including systemic corticosteroids, should be excluded; these include but are not limited to patients with a history of immune related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome, myasthenia gravis; systemic autoimmune disease such as systemic lupus erythematosus (SLE), connective tissue diseases, scleroderma, inflammatory bowel disease (IBD), Crohn's, ulcerative colitis, hepatitis; and patients with a history of toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome should be excluded; patients with vitiligo, endocrine deficiencies including thyroiditis managed with replacement hormones including physiologic corticosteroids are eligible; patients with rheumatoid arthritis and other arthropathies (other than HTLV-associated arthropathy), and psoriasis controlled with topical medication and patients with positive serology, such as antinuclear antibodies (ANA), anti-thyroid antibodies should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible; patients are permitted to enroll if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger (precipitating event)
* Patients who have had evidence of active or acute diverticulitis, intra-abdominal abscess, gastrointestinal (GI) obstruction and abdominal carcinomatosis which are known risk factors for bowel perforation should be evaluated for the potential need for additional treatment before coming on study
* Patients who have hepatitis C (both reactive anti-hepatitis C virus \[HCV\] antibody and detectable HCV RNA) and hepatitis B (hepatitis B surface antigen \[HBsAg\] positive and anti-hepatitis B core \[HBc\]-total positive), may be enrolled, provided their total bilirubin: =\< 1.5 x institutional upper limit of normal (ULN) AST (SGOT)/ALT (SGPT): =\< 2.5 x institutional upper limit of normal
* Patients with concurrent human immunodeficiency virus (HIV) infection may be enrolled if compliant with 3 or more drug anti-retroviral regimen and virus load less than 50 copies/ml and CD4 count greater than 250 cells/ml, and no concurrent opportunistic infection or other malignancy
* Any other prior malignancy from which the patient has been disease free for less than 3 years, with the exception of adequately treated and cured basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of any site or any other cancer
* Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with nivolumab
