目的探讨隆突性皮肤纤维肉瘤(DFSP)的超声表现.方法回顾性分析12例经手术病理证实的隆突性皮肤纤维肉瘤的分布、超声图像特征及彩色多普勒血流成像特点.结果 12例隆突性皮肤纤维肉瘤患者中,11例(91.67%)为单发,直径0.9～8.0 cm;分布在躯干66.67(8/12)、四肢近端16.67%(2/12)、头颈部16.67%(2/12);83.33%(10/12)肿瘤出现在躯干及四肢近端的皮肤与皮肤下层.91.67%(11/12)肿瘤呈不均匀弱回声,66.67%(8/12)边界清楚,形态规则,肿瘤内部无液化或钙化且不伴有局部淋巴结转移;91.67%(11/12)肿瘤内彩色多普勒显示有丰富彩色血流信号.结论患者躯干及四肢近端的皮肤与皮下层肿块,边界清楚、形态规则、内部呈不均匀弱回声、内部血流较丰富、无局部淋巴结肿大是隆突性皮肤纤维肉瘤的超声表现.

Objective To explore the ultrasonographic appearance of dermatofibrosarcoma protuberans. Methods Clinical data, sonographic features and color Doppler flow imaging characteristics of 12 patients surgically and pathologically confirmed dermatofibrosarcoma protuberans were retrospectively analyzed.Results Single mass was detected in 11 patients (11/12, 91.67%) with the diameter ranged 0.9-8.0 cm. The tumors distributed in the trunk (8/12, 66.67%), proximal limbs (2/12, 16.67%) or face and neck (2/12, 16.67%). Most of the tumors (10/12, 83.33%) developed from skin and subcutaneous fat layer of the trunk and limbs and were hypoechoic and heterogeneous (11/12, 91.67%), some (8/12,66.67%) with distinct boundary and regular shape without liquification, calcification nor regional lymph node metastasis. Affluent color Doppler flow signals of tumor were found in 11 patients (91.67%).Conclusion Ultrasonographic characteristics of dermatofibrosarcoma protuberans include distinct boundary, regular shape, heterogeneous hypoechogenicity and rich color Doppler flow signals without regional lymph node metastasis.
