Moreover, NanoString was negative in 1/4 clear‐cell sarcomas (positive by FISH EWSR1 break‐apart assay), 2/5 epithelioid hemangioendotheliomas (positive by FISH for WWTR1‐CAMTA1), and 2/4 inflammatory myofibroblastic tumors (one with ALK rearrangement by FISH and one with EML4 (exon2)‐ALK1 (exon20) by RT‐PCR). This evidence concerns the gene EWSR1 and epithelioid hemangioendothelioma.
