Benign tumors are often seen in breast screening examinations. However, the differential diagnosis is not always simple because of radiological similarity between the different benign lesions.
We present a rare case report of leiomyoma of the breast parenchyma in a 68-year-old asymptomatic patient. The mammographic and ultrasonographic findings were similar to those observed in benign lesions.
The histopathological diagnosis requires careful differentiation from lesions that have smooth muscle proliferation, especially leiomyosarcoma. The most commonly performed treatment is resection of the lesion with free margins. Although breast leiomyoma is rare, it should be considered among the differential diagnoses for breast nodules of benign appearance. Resection with safety margins proved to be the only treatment needed.
良性肿瘤在乳腺筛查检查中经常可见。然而，由于不同良性病变之间的放射学相似性，鉴别诊断并不总是简单的。
我们报告一例罕见的68岁无症状患者乳腺实质平滑肌瘤病例。乳腺X线摄影和超声检查结果与良性病变所见相似。
组织病理学诊断需要与有平滑肌增生的病变仔细鉴别，尤其是平滑肌肉瘤。最常用的治疗方法是切除病变并保证切缘阴性。尽管乳腺平滑肌瘤罕见，但在鉴别诊断外观良性的乳腺结节时应予以考虑。事实证明，切除时保证安全切缘是唯一需要的治疗方法。
