Answer

No specific immunophenotype of unclassifiable myelodysplastic syndromes (MDS-U) exists. However, in cases with a hemodilute aspirate but with 1% peripheral blood blasts, CD34 staining of the bone marrow trephine biopsy may help disclose increased and/or clustered blasts. [11] If blasts appear to comprise at least 5% of the bone marrow biopsy cells by this method, a diagnosis of represent myelodysplastic syndrome (MDS) with excess blasts may be suggested rather than MDS-U.
