摘　　要：目的探讨隆突性皮肤纤维肉瘤(DFSP)的临床及超声声像图特征,帮助提高该病的诊断及鉴别诊断。方法选取我院经病理证实的隆突性皮肤纤维肉瘤患者184例,其中26例有完整的临床资料及术前超声检查,分析26例DFSP患者的临床及超声特征。结果184例DFSP患者(男:女1.33:1.00),肿块发生于躯干104例(56.5%),四肢61例(33.2%),头颈部19例(10.3%)。26例临床资料完整的DFSP患者中2例(7.7%)肿块局限于真皮层内,24例(92.3%)肿块突破真皮层延伸到皮下脂肪层。6例(23.1%)肿块边界不清晰;10例(38.5%)肿块形态不规则。根据肿块内的回声特点,分为3型:Ⅰ型肿块6例(23.1%)表现为均质或不均质低回声,内可见点状、短线状高回声;Ⅱ型肿块18例(69.2%)表现为高、低间杂的混合回声;Ⅲ型肿块2例(7.7%)表现为稍高回声,肿瘤边缘似“假足样”突起。14例(53.8%)肿块后方回声增强,所有病例肿块内均未见钙化。肿块内血流分级:0级3例(11.5%),Ⅰ级8例(30.8%),Ⅱ级7例(26.9%),Ⅲ级8例(30.8%)。所有病例均未发现淋巴结及远处转移。结论DFSP的临床表现和超声图像有一定的特征性。超声检查有助于提高该病的诊断。Objective The sonographic features of dermatofibrosacoma protuberrans have been summarized,in order to assist the diagnosis of the disease.Methods 184 cases histopathologically proven dermatofibrosacoma protuberrans were retrospectively analyzed,in which 26 cases had complete clinical data and preoperative ultrasound examination.The clinical and sonographic features of the 26 cases were summarized.Results Of those 184 cases of dermatofibrosacoma protuberrans,the maleto-female ratio was 1.33:1.00,104 cases(56.5%)occurred in the trunk,61 cases(33.2%)in the limbs,and 19 cases(10.3%)in the head and neck.Among 26 patients,the mass in 2 cases(7.7%)was confined to the dermis,the mass in 24 cases(92.3%)extended to the subcutaneous fat layer.6 cases had unclear boundaries and10 patients had irregular morphology.According to the characteristics of the echo in the mass,they can be divided into three types:there were 6 cases(23.1%)of type I mass,which was homogeneous or heterogeneous hypoechoic,with punctate and short linear hyperechoic,18 cases(69.2%)of type II mass,which presented with mixed echoes of high and low intermingled,and 2 cases(7.7%)of type III mass,which was slightly hyperechoic,"Pseudofoot"protrusions at the margin of the tumor.There were 14 cases(53.8%)with enhanced echo behind the mass,and no calcification was observed in the mass in all cases.The vascularity of the mass was as follows:3 case(11.5%)was grade 0,8 cases(26.9%)were gradeⅠ,7 cases(26.9%)were gradeⅡ,and 8 cases(30.8%)were gradeⅢ.No lymph nodes and metastasis were seen in all cases.Conclusions The clinical and ultrasound images of dermatofibrosarcoma protuberans are characteristic.Ultrasound helps improve the diagnosis of the disease.
