摘要：
原发性前列腺间质肉瘤极为罕见。血清 PSA 通常是正常的。在此，我们报告一例 23 岁男性原发性前列腺间质肉瘤病例。 18F-前列腺特异性膜抗原 (PSMA) PET/CT 显示前列腺肿块和肝脏中多处低密度病变，且 PSMA 高表达。然而，化疗后，前列腺肿块中的 PSMA 表达水平降低，肝脏中的 PSMA 表达病变消失。版权所有 © 2024 Wolters Kluwer Health, Inc. 保留所有权利。
Primary prostatic stromal sarcoma is extremely rare. Serum PSA is usually normal. Here, we report a case of primary prostatic stromal sarcoma in a 23-year-old man. 18F-prostate-specific membrane antigen (PSMA) PET/CT showed prostate mass and multiple low-density lesions in the liver with high PSMA expression. However, after chemotherapy, the level of PSMA expression in the prostate mass decreased, and PSMA expression lesions in the liver disappeared.Copyright © 2024 Wolters Kluwer Health, Inc.
