We report a case of mucinous breast carcinoma whose mammographic features consisted of a suspicious cluster of microcalcifications as the unique sign of malignancy. The lesion was non-palpable and measured approximately 2 cm at the greatest diameter. The microcalcifications showed several morphologies: round, pleomorphic, and fine shapes were identified. The total number of microcalcifications was > 30 and the number per square centimeter varied from 10 to 20. The histological calcifications showed good correlation with the mammographic ones and were localized predominantly at the periphery of the tumor inside ducts with ductal carcinoma in situ or in the acellular mucin. Two types were observed: psammomatous and gross-irregular calcifications. To our knowledge, only one case with similar findings has been reported previously.
我们报告一例黏液性乳腺癌，其乳腺钼靶特征为可疑的微钙化簇，这是恶性肿瘤的唯一征象。该病变触诊不可及，最大直径约2 cm。微钙化呈现多种形态：圆形、异形及细小形态均有发现。微钙化总数>30个，每平方厘米数量在10至20个之间。组织学上的钙化与乳腺钼靶所见有良好相关性，主要位于原位导管癌或无细胞黏液所在导管内肿瘤的周边。观察到两种类型：砂粒体样钙化和粗大不规则钙化。据我们所知，此前仅报道过一例有类似发现的病例。
