Mucinous carcinoma of the breast is one of the rarer forms of intramammary cancer, often presenting as a lobulated, fairly well circumscribed mass on mammography, sonography, and gadolinium-enhanced magnetic resonance imaging. It accounts for 1% to 7% of all breast cancers and generally carries a better prognosis than other types of malignant breast cancers. Metastatic disease occurs at a lower frequency than in other types of invasive carcinoma. We present an atypical case of mucinous carcinoma in a woman who presented with a palpable intramammary lymph node metastasis from an unknown breast primary. Subsequent magnetic resonance imaging and percutaneous biopsy demonstrated histologic findings consistent with a mixed mucinous neoplasm with a micropapillary pattern.
乳腺黏液癌是乳腺内癌症较罕见的形式之一，在乳房X线摄影、超声检查和钆增强磁共振成像中常表现为分叶状、边界相对清晰的肿块。它占所有乳腺癌的1%至7%，总体预后通常比其他类型的恶性乳腺癌要好。转移疾病的发生率低于其他类型的浸润性癌。我们报告一例非典型黏液癌病例，该女性患者表现为可触及的乳腺内淋巴结转移，原发乳腺病灶不明。随后的磁共振成像和经皮活检显示组织学结果符合伴有微乳头模式的混合性黏液性肿瘤。
