JMML: juvenile myelomonocytic leukemia JXG: juvenile xanthogranulomas LCH: Langerhans cell histiocytosis INTRODUCTION Juvenile myelomonocytic leukemia (JMML) is a rare leukemia affecting children. It is known to be associated with multiple juvenile xanthogranulomas (JXG) and neurofibromatosis type 1 and usually presents before the self-resolution of the JXG. Skin rashes may frequently occur with JMML but are most commonly maculopapular type. Leukemia cutis presenting as a Sweet syndromeelike rash has rarely been reported. We present an interesting and atypical case of JMML in a child with a history of resolved JXG, presenting with leukemia cutis as the first sign of JMML. Histology of the skin rash showed atypical leukemic infiltrates.
