And phyllodes tumor of the breast with tonsillar metastasis is very rare.Case presentationA 57-year-old Japanese woman received surgery (partial mastectomy) of malignant phyllodes tumor. Seven months after initial surgery, pharyngeal pain, swelling, and a feeling of dyspnea developed, and tumor was found in the left palatine tonsil. Computed tomography for further evaluation showed a tonsillar lesion with contrast enhancement, and tonsillar metastasis was suspected. The metastatic lung tumors had not progressed. Laryngoscopic biopsy showed a tonsillar metastasis from the malignant phyllodes tumor. Despite the diagnosis of malignant phyllodes tumor with tonsillar and pulmonary metastases, the patient refused further treatment and died about 1 month later.ConclusionsA patient with a malignant phyllodes tumor of the breast and tonsillar metastasis was reported, along with a discussion of the relevant literature of this very rare pattern of metastasis.
