• chronic myelomonocytic leukemia
  27 August 2012

  CMML; CMMOL
  Definition: Chronic myelomonocytic leukemia (CMML or CCMOL) is a rare clonal hematopoietic disorder.
  Cutaneous CMML tumors
  Chronic myelomonocytic leukemia (CMML) can also involve the skin.
  A minimal panel of immunohistochemical markers including CD68, CD1a, S100, Langerin, and CD123 is necessary to make the correct classification in this spectrum of cutaneous CMML tumors, in which dendritic cell lineage plays an important role.
