肌内黏液瘤的临床特点研究及文献回顾

Clinicopathological characteristics of intramuscular myxoma and literatures review

目的：探讨肌内黏液瘤的临床及病理特点，提高对本疾病诊断治疗的认识。方法回顾性分析2例肌内黏液瘤进行临床诊断治疗和病理特点，应用免疫组化染色分析明确诊断，并复习最新文献进展。结果肿瘤临床症状不典型，MRI 表现为 T1W1低信号，T2W1高信号，镜下见肿瘤有稀少的星形细胞和梭形细胞以及丰富的黏液基质，边缘性切除肿瘤。结论肌内黏液瘤是罕见的软组织良性肿瘤，影像学和病理可以明确诊断，手术切除可以治愈。
