| 目的 探讨皮肤鳞状细胞癌的高频超声图像特征。方法 回顾性分析51例经组织病理证实的皮肤鳞状细胞癌的超声图像，观察声像图特征及内部血流情况。结果 共发现53个病灶，其中35个病灶位于头面部，15个位于四肢，2个位于腰部，1个位于胸壁。病灶深度平均（8.38±5.28） mm，其中43个病灶深度≤10 mm；最大径平均为（22.45±12.71） mm。15个病灶位于皮肤层，38个位于皮肤及皮下层。23个病灶边界清晰，30个边界不清。16个病灶形态规则，37个形态不规则。31个病灶表皮层角化增厚。20个病灶后方回声无明显变化，24个后方回声衰减，9个后方回声增强。2个病灶内可见钙化灶，1个伴有液化。病灶血流Alder分级：0级7个，1级12个，2级4个，3级30个。对35个病灶进行了良恶性诊断，诊断为恶性33个（33/35，94.29%），良性2个（2/35，5.71%）。结论 皮肤鳞状细胞癌常表现为低回声、边界不清、形态不规则、表皮层增厚，后方回声可衰减或增强以及血供丰富。超声检查有助于诊断皮肤鳞状细胞癌。 |

| Objective To assess the high frequency ultrasonographic features of squamous cell carcinoma (SCC) of skin. Methods High frequency color Doppler ultrasound images of 51 patients with SCC confirmed by pathology were analyzed retrospectively. The ultrasonographic features and internal blood flow were observed. Results Totally 53 lesions were found with 35 lesions located on face, 15 on limbs, 2 on waist and 1 on chest wall. The average depth was (8.38±5.28)mm and the depth of 43 lesions were less than 10 mm. The average diameter was (22.45±12.71)mm. Fifteen lesions located in the skin layer and 38 located in the skin and subcutaneous layer. The boundaries were clear in 23 lesions and unclear in 30. There were 16 lesions of tabular mass and 37 of irregular mass. Thirty-one lesions were epidermal keratinization thickening. Rear echo of 20 lesions had no obvious change, and 24 posterior acoustic attenuation, 9 posterior acoustic enhancement. Calcifications were found in 2 lesions and liquification was found in 1 lesion. The Alder grade of internal blood flow signals were grade 0 in 7 lesions, grade 1 in 12, grade 2 in 4 and grade 3 in 30, respectively. Thirty-three (33/35,94.29%) in 35 lesions were diagnosed as malignant and 2 (2/35,5.71%) were diagnosed as benign. Conclusion The ultrasonographic features of SCC including hypo echo, unclear boundaries, irregular form, epidermal keratinization thickening and plenty of blood flow. Ultrasonography is helpful in diagnosis of SCC of skin. |
