Also, two tumors with morphologic feature of LG‐ESS have had YWHAE rearrangements: a YWHAE/NUTM2A fusion was identified in a tumor confined within the endometrium,72 whereas deletion of a 3′ probe for YWHAE was shown in an LG‐ESS and in its recurrence in a case showing progression from LG‐ to HG‐ESS.73 The gene discussed is NUTM2A; the disease is neoplasm.
