Dermatofibrosarcoma protuberans is a rare soft tissue sarcoma with a high recurrence rate. Herein, we present 68Ga-FAPI and 18F-FDG PET/CT findings of dermatofibrosarcoma protuberans in a 45-year-old man. Dermatofibrosarcoma protuberans only shows limited FDG uptakes on 18F-FDG PET/CT, but demonstrated intense tracer uptakes on 68Ga-FAPI PET/CT. In this case, 68Ga-FAPI was superior to 18F-FDG PET/CT in detecting dermatofibrosarcoma protuberans.
隆突性皮肤纤维肉瘤是一种罕见的软组织肉瘤，具有较高的复发率。在此，我们报告一例 45 岁男性隆突性皮肤纤维肉瘤的 68Ga-FAPI 和 18F-FDG PET/CT 表现。隆突性皮肤纤维肉瘤在 18F-FDG PET/CT 上仅显示有限的 FDG 摄取，但在 68Ga-FAPI PET/CT 上显示出强烈的示踪剂摄取。在本例中，68Ga-FAPI 在检测隆突性皮肤纤维肉瘤方面优于 18F-FDG PET/CT。
