EWSR1 and vascular malformation: While the vascular malformations/hemangiomas with EWSR1-NFATC2 rearrangement reported here also show the presence of thick-walled vessels, for the EWSR1-NFATC2 rearranged hemangioma the presence of only thin-walled vessels of varying caliber, embedded in a loose fibrous stroma is reported.29 However, no conclusions can be drawn as case numbers are very small.
