To determine the efficacy of ultrasonography for the diagnosis of subcutaneous benign lesions.
Retrospective study.
Tokyo Kousei-Nenkin Hospital, Tokyo, Japan. Patients The study included 183 patients with subcutaneous benign lesions who underwent ultrasonography and then received a pathologic diagnosis after surgery.
The study evaluated the number of cases in which the preoperative diagnosis after ultrasonography or just after palpation agreed with the pathologic diagnosis.
Ultrasonography significantly increased the preoperative diagnostic yield of subcutaneous benign lesions (after palpation, 29%; after ultrasonography, 46%; P < .001). The sensitivity for the diagnosis of lipoma (after palpation, 54.8%; after ultrasonography, 88.1%; P < .01) and the specificity for the diagnosis of epidermal cyst (after palpation, 93.5%; after ultrasonography, 99.3%; P < .05) significantly increased after ultrasonography. The sensitivity for the diagnosis of epidermal cyst and ganglion also tended to increase after ultrasonography. Conclusion The study results suggest that ultrasonography is useful for the preoperative examination of subcutaneous benign lesions.
确定超声检查对皮下良性病变的诊断效能。
回顾性研究。
日本东京东京厚生年金医院。患者本研究纳入了183例皮下良性病变患者，这些患者接受了超声检查，随后在手术后获得病理诊断。
本研究评估了超声检查后或仅触诊后术前诊断与病理诊断一致的病例数。
超声检查显著提高了皮下良性病变的术前诊断率（触诊后为29%；超声检查后为46%；P <.001）。超声检查后，脂肪瘤诊断的敏感性（触诊后为54.8%；超声检查后为88.1%；P <.01）和表皮样囊肿诊断的特异性（触诊后为93.5%；超声检查后为99.3%；P <.05）显著提高。超声检查后，表皮样囊肿和腱鞘囊肿诊断的敏感性也有增加趋势。结论研究结果表明，超声检查对皮下良性病变的术前检查有用。
