title: Lethal skin cancers in hairy cell leukemia (two case reports).
abstract: 2 patients with hairy cell leukemia (HCL) complicated by multiple cutaneous and other malignancies are described. The second malignancies behaved in a much more aggressive fashion than would be expected in an immunocompetent population, and were lethal in both patients. The literature regarding second malignancies in immune compromised patients, and in HCL in particular, is reviewed.
