107例基底细胞癌的高频超声特点

Features of ultrasound in skin basal cell carcinoma

回顾性分析经病理证实的107例BCC患者的声像图(其中结节溃疡型63例、色素型22例、表浅型20例、纤维上皮瘤型1例、硬斑病型1例)。BCC的圆度系数值为1.43~17.75,平均值8.53,中位数3;22例探及血流信号,收缩期峰值流速(PSV)平均值为14.23±4.77 cm/s,阻力指数(RI)平均值为0.44±0.13。结节溃疡型、色素型和纤维上皮瘤型皮损回声形态表现为椭圆形或类圆形68例,扁平形18例,位于真皮层内62例;表浅型、硬斑病型皮损回声形态表现为椭圆形或类圆形2例,扁平形19例、位于真皮层内2例。

The sonogram features of 107 cases with basal cell carcinoma（ 63 of nodulo-ulcerative type,22 of pigmented type,20 of superficial type and one of morphea type and one of fibroepithelioma type） confirmed by pathology were analyzed retrospectively. The roundness index ranged from 1.43 to 17.75 with an average value of 8.53 and a median value of 3. Blood flow signals were found in 22 cases with an average peak systolic velocity（ PSV） of 14.23± 4.77cm/s and an average resistance index（ RI） of 0.44± 0. 13. The sonogram of the lesions in the patients with nodulo-ulcerative type,pigmented type and fibroepithelioma type were oval or quasi-circular homogeneous in 68 patients,flat in 18 and the lesions in the dermis in 62 cases. The sonogram of the lesions in the patients with superficial type and morphea type were oval or quasi-circular homogeneous in 2 patients and flat in 19,and the lesions in the dermis in 2 cases.
