OBJECTIVE
Mucinous carcinoma is a rare, special subtype of breast carcinoma associated with a good prognosis. It often presents a confusing appearance with a benign process. For all these reasons, differential diagnosis could be challenging.
CASE REPORT
Eighty years-old woman with a soft, lobulated, and well circumscribed mass at the left breast mimicking a benign process. Pathological examination of a core needle biopsy showed pure mucinous carcinoma.
DISCUSSION
It is a disease of elderly patient, over 60 years, and usually occurs in postmenopausal women. It accounts for only 2% of total breast carcinomas. On pathologic analysis, to be defined as pure mucinous carcinoma, a carcinoma must be made up of at least 90% intracellular or extracellular mucin.
CONCLUSION
Examination of core biopsy material should be done carefully respecting this criteria to confirm the diagnosis of this rare entity and eliminate differential diagnosis.
目的
黏液癌是一种罕见的特殊类型乳腺癌，预后良好。它常表现出与良性病变相似的外观，因此鉴别诊断具有挑战性。
病例报告
一名80岁女性，左乳有一个柔软、分叶状且边界清晰的肿块，看似良性病变。粗针穿刺活检的病理检查显示为纯黏液癌。
讨论
这是一种老年患者（60岁以上）的疾病，通常发生在绝经后女性中。它仅占乳腺癌总数的2%。在病理分析中，要被定义为纯黏液癌，癌组织必须至少由90%的细胞内或细胞外黏液组成。
结论
应仔细按照此标准检查粗针活检材料，以确诊这种罕见疾病并排除鉴别诊断。
