FOLH1 and neoplasm: Focusing only on the PSMA expression in the neovasculature of these high grade sarcomas, we noted that the neovasculature of 2/20 pleomorphic liposarcomas (10%), 3/29 angiosarcomas of the soft tissue (10.34%), 1/8 alveolar rhabdomyosarcomas (12.50%) and 2/5 pleomorphic rhabdomyosarcomas (40%) showed a strong expression (labelling index = 2) in more than 10% of the investigated cases, whereas only 6/106 (5.66%) of the investigated Ewing sarcomas presented a strong expression (labelling index = 2) in the tumor-associated neovasculature.
