A 75-year-old woman consulted our hospital for a lump on her left breast. The tumor was 5 cm in diameter and was palpable in the ABE area. The tumor was identified as an intra-cystic tumor using ultrasonography. Contrast-enhanced magnetic resonance imaging showed a tumor with cystic components that were slowly stained in a dynamic study. A fine needle aspiration biopsywas performed, and the pathological diagnosis was class V. Metastatic work-up revealed no evidence of metastasis. Therefore, we determined the clinical stage as T3N0M0, stage II B. Breast reduction surgeryand sentinel lymph node biopsywere performed on the left breast. The histopathological findings from the surgicallyresected specimens showed mucinous components with some invasive ductal components. Therefore, the pathological diagnosis was mixed mucinous carcinoma of the breast. The tumor size was 8 cm in diameter. Here, we report a case of mucinous carcinoma that showed a huge intra-cystic tumor, which is rarely described in the literature.
一名75岁女性因左侧乳房肿块前来我院就诊。肿瘤直径为5厘米，在ABE区域可触及。通过超声检查，该肿瘤被确定为囊内肿瘤。对比增强磁共振成像显示，在动态研究中，肿瘤的囊性成分呈缓慢染色。进行了细针穿刺活检，病理诊断为V级。转移检查未发现转移迹象。因此，我们将临床分期确定为T3N0M0，II B期。对左侧乳房进行了乳房缩小手术和前哨淋巴结活检。手术切除标本的组织病理学检查结果显示为黏液性成分伴一些浸润性导管成分。因此，病理诊断为乳腺黏液腺癌。肿瘤大小为直径8厘米。在此，我们报告一例黏液腺癌病例，该病例表现为巨大的囊内肿瘤，这在文献中很少有描述。
