Most present as breast masses in women of child-bearing age. A 29-year-old female presented with a swollen, firm and tender right breast, initially misdiagnosed as mastitis. Core needle biopsy revealed findings consistent with granulomatous lobular mastitis, and cultures were all negative for an infectious etiology. She was started on steroid therapy to which she initially responded well. A few weeks later she deteriorated and was found to have multiple breast abscesses. She underwent operative drainage and cultures grew Mycobacterium fortuitum. Granulomatous lobular mastitis is a rare inflammatory disease of the breast. The definitive diagnose entails a biopsy. Other causes of chronic or granulomatous mastitis should be ruled out, including atypical or rare bacteria such as Mycobacterium fortuitum. This is the first reported case of granulomatous mastitis secondary to Mycobacterium fortuitum. With pathologic confirmation of granulomatous mastitis, an infectious etiology must be ruled out. Atypical bacteria such as Mycobacterium fortuitum may not readily grow on cultures, as with our case. Medical management is appropriate, with surgical excision reserved for refractory cases or for drainage of abscesses.展开更多
目的:系统评价肉芽肿性小叶性乳腺炎(GLM)的复发情况。方法:计算机检索中国知网(CNKI)、万方数据库(WanFang Database)、中国生物医学文献数据库(CBM)、维普数据库(VIP)、PubMed、Web of Science、EMbase,搜集有关GLM复发因素相关的研究...目的:系统评价肉芽肿性小叶性乳腺炎(GLM)的复发情况。方法:计算机检索中国知网(CNKI)、万方数据库(WanFang Database)、中国生物医学文献数据库(CBM)、维普数据库(VIP)、PubMed、Web of Science、EMbase,搜集有关GLM复发因素相关的研究,检索时限为建库至2023年5月16日。结果:最终纳入9篇文献,涉及1741例GLM病人。Meta分析结果显示:GLM复发率为16%[95%CI(12%,21%)],影响因素分析显示,棒状杆菌感染[OR=4.80,95%CI(1.76,13.09),P<0.01]、吸烟[OR=11.01,95%CI(1.14,106.78),P<0.05]等是GLM复发的独立危险因素。结论:现有证据表明,GLM复发率较高,且受棒状杆菌感染和吸烟等因素的影响,受纳入研究数量的限制,研究结果尚待更多高质量研究予以验证。展开更多
