Diagnosis of melanoma and chronic lymphocytic leukemia (CLL), and history of keratinocyte carcinoma (KC). Venn diagram of groups of patients as defined by history of keratinocyte carcinoma (KC) and diagnosis of melanoma and/or chronic lymphocytic leukemia (CLL). Patients with both melanoma and CLL were more likely to have a history of KC (41%) compared to patients diagnosed with only CLL (19%) or patients diagnosed with only melanoma (29%)
