Editing Myeloid sarcoma (section)

=== In myeloproliferative or myelodysplastic syndromes ===
Chloromas may occur in patients with a diagnosis of [[myelodysplastic syndrome]] (MDS) or [[myeloproliferative syndrome]]s (MPS) (e.g. [[chronic myelogenous leukemia]] (CML), [[polycythemia vera]], [[essential thrombocytosis]], or [[myelofibrosis]]). The detection of a chloroma is considered ''de facto'' evidence these premalignant conditions have transformed into an acute leukemia requiring appropriate treatment. For example, presence of a chloroma is sufficient to indicate chronic myelogenous leukemia has entered its 'blast crisis' phase.
