目的:探讨结节型恶性黑色素瘤在左小腿的超声表现。方法:分析本组1例男性藏族患者左下肢外踝皮肤肿块彩色多普勒超声及MRI检查表现,并经手术后病理证实。结果:左下肢外踝不均质等回声包块,术后病理结果为结节型恶性黑色素瘤。结论:恶性黑色素瘤是一种恶性程度极高的肿瘤。对于浅表组织肿物,尤其超声表现不典型者,还需高度重视多切面、多角度反复扫查,且与临床资料及其他辅助检查结合避免漏诊、误诊。
Objective: To investigate the ultrasonographic features of nodular malignant melanoma in the left leg. Methods: Color Doppler ultrasonography and MRI examination of the left lower extremity lateral malleolus skin mass in 1 Tibetan male patient in this group were analyzed and confirmed by pathology. Results: The left lower extremity ankle was not homogeneous and other echogenic mass. The pathological result was nodular malignant melanoma. Conclusion: Malignant melanoma is a highly malignant tumor. For superficial tissue masses, especially those with atypical ultrasound performance, we need to attach great importance to multi-slice and multi-angle repeated scanning. Combined with clinical data and other auxiliary examinations, we should avoid misdiagnosis and misdiagnosis.
