title: Atypical myeloproliferative disorders in adults.
abstract: The definition of 'atypical MPDs' includes all chronic myeloid disorders that defy classification as either MDS or classic MPDs. These can be both molecularly defined or clinicopathologically assigned: chronic myelomonocytic leukemia, juvenile myelomonocytic leukemia, chronic neutrophilic leukemia, chronic basophilic leukemia, chronic eosinophilic leukemia, idiopathic eosinophilia including hypereosinophilic syndrome, systemic mastocytosis, unclassified MPD, and eosinophilic/mast cell disorders associated with mutations of PDGFR, FGFR1, and KIT all fall under the category of atypical MPDs.
