摘要 通过分析浙江省杭州市萧山区第一人民医院2012年收集的1例乳腺微腺体腺病相关产基质的癌(Microglandular Adenosis Relevant Matrix-producing Carcinoma,MGARMPC)其病理资料。此病例镜下由MPC(占60%)、MGA(占30%)和非典型微腺体腺病(atypical microglandular adenosis,AMGA)(占10%)构成。MPC区域腺上皮呈实性、条索状改变,细胞轻度异型,其周围缺乏基底膜。间质直接过渡为黏液软骨样基质。MGA可见温和单层及立方样细胞呈腺管样排列,弥漫分布于正常乳腺间质及脂肪中,间质无明确促结缔组织反应,腔内可见嗜伊红分泌物。AMGA区域散在异型腺体夹杂在MGA的腺管周围,可见移行过渡。免疫表型:肿瘤细胞ER、PR、HER-2均为阴性,S-100阳性,SMA和P63阴性。MGARMPC罕见,诊断需依赖病理明确。
