Marginal zone lymphoma of mucosa-associated lymphoid tissue is a B-cell lymphoma which arises in extranodal sites, most commonly the stomach. Involvement of the breast is very rare. We present a case of an asymptomatic 63-year-old woman with synchronous mucosa-associated lymphoid tissue lymphoma involving both breasts and subcutaneous tissues. This represents a form of secondary breast lymphoma (given the concurrent involvement of the breast and non-mammary organ systems) and is an exceedingly rare diagnosis which, to our knowledge, has only been discussed in a few case series.
黏膜相关淋巴组织边缘区淋巴瘤是一种发生于结外部位的B细胞淋巴瘤，最常见于胃部。乳腺受累极为罕见。我们报告一例63岁无症状女性，同时发生双侧乳腺及皮下组织的黏膜相关淋巴组织淋巴瘤。这代表了一种继发性乳腺淋巴瘤（鉴于乳腺和非乳腺器官系统同时受累），是一种极为罕见的诊断，据我们所知，仅在少数病例系列中有过讨论。
