title: A 27-Year-Old Patient Fulfilling the Diagnostic Criteria of Both CMML and JMML.
abstract: Chronic myelomonocytic leukaemia (CMML) and juvenile myelomonocytic leukaemia (JMML) are two disease entities that come under the myelodysplastic/myeloproliferative neoplasms category. Each of the two conditions has its own diagnostic criteria. In addition, they have different ages of presentation; while CMML is typically a disease of the elderly, JMML is a disease of young children. Here we are presenting the case of a 27-year-old male patient who, at the time of diagnosis, fulfilled the diagnostic criteria of both diseases. In addition he had radiological changes of type 1 neurofibromatosis. Possible explanations of the patient case have been discussed.
