INTRODUCTION
Breast tumor metastasis to the tonsil is extremely rare.
PRESENTATION OF CASE
A 54-year-old woman underwent resection of a breast malignant phyllodes tumor and later presented with metastasis to the lung and the left tonsil. She underwent left lower lobectomy and resection of the left tonsillar tumor. She subsequently developed undifferentiated carcinoma of the right tonsil. She underwent resection of the right tonsillar tumor and chemotherapy was started. The central venous catheter became infected with methicillin-resistant Staphylococcus aureus. Finally, she died.
DISCUSSION
To the best of our knowledge, this is the first reported case of a phyllodes tumor metastasizing to the tonsil. Furthermore, morphological and immunohistochemical study revealed that the right tonsillar tumor was irrelevant to the phyllodes tumors.
CONCLUSION
We report a case of phyllodes tumor metastasis to the left tonsil which developed undifferentiated carcinoma in the other side of tonsil later. Breast tumor metastasis to the tonsil is rare but it should be considered as a possible diagnosis.
引言
乳腺肿瘤转移至扁桃体极为罕见。
病例介绍
一名54岁女性接受了乳腺恶性叶状肿瘤切除术，随后出现肺和左侧扁桃体转移。她接受了左下肺叶切除术和左侧扁桃体肿瘤切除术。随后她又患上了右侧扁桃体未分化癌。她接受了右侧扁桃体肿瘤切除术并开始化疗。中心静脉导管感染了耐甲氧西林金黄色葡萄球菌。最终，她去世了。
讨论
据我们所知，这是首例报道的叶状肿瘤转移至扁桃体的病例。此外，形态学和免疫组化研究表明，右侧扁桃体肿瘤与叶状肿瘤无关。
结论
我们报告了一例叶状肿瘤转移至左侧扁桃体，随后另一侧扁桃体发生未分化癌的病例。乳腺肿瘤转移至扁桃体虽罕见，但应将其视为一种可能的诊断。
