 The molecular hallmark of angiomatoid fibrous histiocytoma (AFH) is not well defined, with only six cases with specific gene fusions reported to date, consisting of either FUS-ATF1 or EWSR1-ATF1.     ///    "To address this, we investigated the presence of FUS-ATF1, EWSR1-ATF1, and the highly related EWSR1-CREB1 fusion in a group of nine AFHs.
