Our retrospective analysis explored the role of leukemia cutis (LC) in disease progression of chronic myelomonocytic leukemia (CMML). Of 108 patients with CMML, 11 patients (10.2%) had LC including its equivalent (2 patients). Four of these patients developed acute myeloid leukemia (AML) within 0-4 months. The remaining 7 patients demonstrated increased monocytes (<20% blasts), with 3 demonstrating extramedullary involvement. Overall survival from LC to disease progression was 7.8 months. Overall survival from diagnosis to the last follow-up in patients with LC was 28.2 months, shorter than patients without LC (44 months). LC and its equivalent could predict disease progression to AML.
