Smooth muscle neoplasms exist as a spectrum of pathologic processes ranging from benign leiomyoma to anaplastic leiomyosarcoma. Although these tumors typically occur in regions where there is an abundance of smooth muscle, they may also be derived from the muscularis of the gastrointestinal tract or the media of blood vessels. The majority of breast leiomyomas are contiguous with the muscular components of the nipple areolar complex. Strong, in 1913, is credited with the early descriptions of leiomyoma of the mammary gland. There have been relatively few reports of this entity since Strong's initial description. Smooth muscle neoplasms of the breast present unique clinical challenges for which therapeutic decisions are based on criteria extrapolated from the management of similar tumors at other sites. This report high-lights key clinical and pathologic findings in a postmenopausal woman with a discrete breast mass of benign smooth muscle histology.
平滑肌肿瘤涵盖了一系列病理过程，从良性平滑肌瘤到间变性平滑肌肉瘤。尽管这些肿瘤通常发生在平滑肌丰富的区域，但它们也可能起源于胃肠道的肌层或血管的中膜。大多数乳腺平滑肌瘤与乳头乳晕复合体的肌肉成分相邻。1913年，斯特朗首次对乳腺平滑肌瘤进行了描述。自斯特朗最初描述以来，关于这个实体的报道相对较少。乳腺平滑肌肿瘤带来了独特的临床挑战，其治疗决策基于从其他部位类似肿瘤的管理中推断出的标准。本报告重点介绍了一位绝经后女性患有组织学为良性平滑肌的离散乳腺肿块的关键临床和病理发现。
