Abstract：
BACKGROUND: This case report presents a rare occurrence of lupus mastitis affecting the breast.
METHODS: An induration with mild discomfort was detected in the upper inner quadrant of the right breast of a 27-year-old Chinese woman with regular menstrual cycles. The patient is currently unmarried and has no previous history of full-term pregnancies or lactation. An ill-defined, subcutaneous, hyperechoic lesion with no calcification was visualized on breast ultrasound. Peripheral and internal blood flow signals demonstrated high intensity. Pathological analysis of a breast needle biopsy revealed fat lobule necrosis accompanied by mixed lymphoplasmacytic and histiocytic aggregates.
CONCLUSIONS: The diagnosis of lupus mastitis necessitates a comprehensive evaluation of the patient\'s medical history, serological testing, imaging studies, and histopathological analysis.

方法：在一名27岁的中国女性，月经周期规律，在右乳房的上内象限发现了轻度不适的硬结。患者目前未婚，以前没有足月妊娠或哺乳史。一个不明确的，皮下,乳腺超声检查显示无钙化的高回声病变。外周和内部血流信号显示高强度。乳腺穿刺活检的病理分析显示，脂肪小叶坏死伴有混合的淋巴浆细胞和组织细胞聚集体。
结论：狼疮乳腺炎的诊断需要对患者的病史进行全面评估，血清学检测,影像学检查,和组织病理学分析。
