Overcoming immunosurveillance is a major step in the progression of many types of tumors. Several immune escape strategies have been identified, including immunoediting and the establishment of an immune suppressive microenvironment. The aim of the present study was to determine whether the hereditary or sporadic context has any influence in the relationship between immune surveillance and tumor development, using sporadic and familial adenomatous polyposis related colorectal adenomas as a model. ⋯ This study shows that sporadic lesions harbor higher tumor-infiltrating immune cell counts, which might reflect a higher immune tolerance towards hereditary lesions.

Immune checkpoint inhibitors revolutionized anti-neoplastic treatment. Recently, the European Medicines Agency and the United States Food and Drug Administration approved inhibitors of various immune checkpoints, namely the cytotoxic T-lymphocyte-associated protein 4, programmed cell death protein 1 and its ligand. Despite the added benefits in the treatment of several neoplasms, immune checkpoint blockade may also be associated with multiple immune-related adverse events. ⋯ Given the high rate of cutaneous toxicity associated with new immune checkpoint inhibitors and their impact on quality of life, their early recognition and appropriate approach are crucial in the treatment of cancer patients. Observation by a dermatologist should be provided in patients with certain toxicities.
