Minute pulmonary meningothelial-like nodules (MPMNs) are incidentally found lesions in lung resection specimens and autopsies. MPMNs have been associated with neoplastic and non-neoplastic pulmonary conditions and occasionally with extrapulmonary diseases. We report a case of a female patient presenting with invasive lobular carcinoma of the breast and MPMNs, masquerading as metastatic deposits. We describe the morphological, immunohistochemical and ultrastructural features of MPMNs and emphasize the importance of their recognition for proper staging and treatment of patients. To our knowledge, this is the first case in the English literature describing this coexistence.
微小肺脑膜上皮样结节(MPMNs)是在肺切除标本和尸检中偶然发现的病变。MPMNs与肿瘤性和非肿瘤性肺部疾病有关,偶尔也与肺外疾病有关。我们报告一例女性患者,患有乳腺浸润性小叶癌和MPMNs,后者伪装成转移灶。我们描述了MPMNs的形态学、免疫组织化学和超微结构特征,并强调识别它们对于患者正确分期和治疗的重要性。据我们所知,这是英文文献中描述这种共存情况的首例病例。
