We herein report a rare case of collision lymph node metastases of breast and thyroid carcinomas. A 49-year-old female had undergone an extensively radical mastectomy of the right breast for inflammatory breast cancer at our hospital. Eleven months later, she presented with enlarged lymph nodes in her right lateral neck and multiple nodules in bilateral thyroid lobes. The patient underwent total thyroidectomy and radical dissection of the bilateral cervical lymph nodes. A histological examination showed multiple foci of papillary thyroid carcinoma (PTC) in the bilateral lobes. Surprisingly, concurrent metastases of breast carcinoma and PTC were shown in one of the lymph nodes from the right jugular region. This rare case of collision metastasis and the related literature are discussed.
我们在此报告一例乳腺癌和甲状腺癌碰撞淋巴结转移的罕见病例。一名 49 岁女性曾因炎性乳腺癌在我院行右乳腺癌广泛根治性切除术。11 个月后，她出现右侧颈外侧淋巴结肿大和双侧甲状腺叶多个结节。患者行甲状腺全切除术和双侧颈淋巴结根治性清扫术。组织学检查显示双侧叶有多个甲状腺乳头状癌（PTC）病灶。令人惊讶的是，右侧颈静脉区域的一个淋巴结中同时显示乳腺癌和 PTC 的转移。讨论了这种罕见的碰撞转移病例及相关文献。
