No association with the rarer skin cancer, the Merkel cell tumour (MCT), has previously been reported. Two patients with MCT had a previous diagnosis of CLL. MCT is an aggressive skin cancer, as up to 45% of patients have lymph node involvement at presentation and 5-year disease-free survival is as low as 30%. It is most commonly found on sun-exposed areas of the body, and ultraviolet radiation together with drug-induced or CLL-induced immunosuppression may be the underlying mechanism in the observed relationship between CLL and other skin cancers.<\/jats:p>","DOI":"10.1046\/j.1365-2133.2000.03370.x","type":"journal-article","created":{"date-parts":[[2003,3,11]],"date-time":"2003-03-11T05:24:51Z","timestamp":1047360291000},"page":"525-528","source":"Crossref","is-referenced-by-count":71,"title":["Two
