Breast cancers of either ductal or lobular pathology make up the vast majority of breast malignancies. Other cancers occur rarely in the breast. Benign pathology can at times mimic breast cancers on imaging and initial needle biopsies. We report a rare breast pathology of cylindroma. Cylindromas are usually benign, rare dermatologic lesions most commonly associated with head or neck locations. They more commonly occur as sporadic and solitary masses. Less commonly is an autosomal-dominant multi-centric form of this disease. Malignant cylindromas are very rare. We present a patient with findings of a cylindroma of the breast after excision. This was initially felt to be concerning for breast cancer on imaging and core biopsy. Treatment of cylindromas of the breast is excision. Sentinel lymph node dissection is not indicated, nor are adjuvant therapies when identified in the breast. This lesion needs to be included in the differential diagnosis for breast cancer. If cylindromas can be accurately diagnosed preoperatively, this would negate the need for consideration of axillary nodal surgery and adjuvant therapies.
乳腺的导管或小叶病理学癌症构成了绝大多数的乳腺恶性肿瘤。其他癌症在乳腺中很少见。良性病理学有时在影像学和初始针吸活检上可模拟乳腺癌。我们报告了一种罕见的乳腺圆柱瘤病。圆柱瘤通常是良性的，罕见的皮肤病变，最常与头部或颈部位置相关。它们更常以散发性和孤立性肿块的形式发生。较少见的是这种疾病的常染色体显性多中心形式。恶性圆柱瘤非常罕见。我们报告了一名患者的乳腺圆柱瘤的检查结果。在影像学和核心活检上，最初认为这是乳腺癌。乳腺圆柱瘤的治疗方法是切除。不需要进行前哨淋巴结切除术，也不需要在乳腺中发现时进行辅助治疗。这种病变需要在乳腺癌的鉴别诊断中考虑。如果圆柱瘤可以在术前准确诊断，这将消除对腋窝淋巴结手术和辅助治疗的考虑。
