年7月12日，《美国医学会杂志外科学分册》在线发表意大利医院、比萨大学的病例报告：年轻女性新生乳房肿块一例。
患者女性，28岁，急诊入院，主诉左乳上方突发扩散性疼痛伴水肿并可扪及腋窝淋巴结，不伴炎症或感染的临床症状（图1A）。无发热、无皮肤发红，但有乏力。
图1、患者初步表现。A、左乳上方不规则肿块。B、乳房超声提示乳腺组织低回声伴导管周围小囊肿。
患者于急诊入院前10个月停止哺乳，近期有肺炎并自行使用抗生素史，无乳腺癌或卵巢癌家族史，无药物成瘾史，无乳房透明质酸或硅胶注射史，否认乳房创伤史。
体检：乳房肿块大小6cm，质硬，无乳头溢液或内陷，左腋可扪及淋巴结。
乳房超声提示乳腺组织弥漫性非特异性低回声伴导管周围小囊肿（图1B）。乳腺钼靶提示左上象限扭曲、密度不均。
左乳上方多次14G超声引导活检和肿大淋巴结细针抽吸细胞学检查提示为肉芽肿性炎症伴上皮样组织细胞、淋巴细胞、浆细胞、嗜酸性粒细胞，淋巴结正常。
血液检测结果：乙型肝炎表面抗原、丙型肝炎抗体、人体免疫缺陷病毒酶联免疫吸附试验、全血γ干扰素释放试验（QuantiFERON）阴性，IgG巨细胞病毒阳性，纤维蛋白原mg/dL（6.88μmol/L），红细胞沉降率：4mm/h，白细胞计数：/uL（7.66×10+9/L）；无获得性免疫抑制；无血液病变。
