Myoid hamartomas of the breast are extremely rare breast lesions, with a poorly understood pathogenesis. We describe the case of a 38-year-old premenopausal woman who presenting with a mass in the left breast. Mammography revealed an oval mass that was partly indistinct, and ultrasonography showed a hypoechoic mass with a slightly irregular margin. Bilateral breast dynamic magnetic resonance imaging was performed for a more detailed evaluation. The images showed rapid initial enhancement and a microlobulated margin. Because the suspicion of malignancy was strong at that time, core needle biopsy was performed. Histologically, the tumor was identified as fibroadenoma. A case of myoid hamartoma of the breast that proved difficult to diagnose is reported, and discussed with reference to the literature.
乳腺肌样错构瘤极为罕见，其发病机制尚未完全阐明。我们报告了 1 例 38 岁绝经前女性，左乳出现肿块。乳腺 X 线摄影显示卵圆形部分边界不清的肿块，超声显示低回声肿块，边界略不规则。行双侧乳腺动态磁共振成像检查以进行更详细的评估。图像显示快速初始增强和微分叶状边缘。由于当时强烈怀疑恶性肿瘤，进行了空心针活检。组织学上，肿瘤被确定为纤维腺瘤。报告了 1 例乳腺肌样错构瘤病例，该病例诊断困难，并结合文献进行了讨论。
