We present a 73-year-old female with advanced thyroid papillary carcinoma who complained of gross hematuria. We found a bladder tumor and considered it the cause of her symptom. Cystoscopic findings of the tumor were unusual, with peri-tumor vessel formation. Pathological examination of the bladder tumor was consistent with metastasis of thyroid papillary carcinoma. Therefore, we identified thyroid carcinoma metastasis to the urinary bladder as the cause of hematuria in our patient. Thyroid carcinoma metastasis to the bladder is extremely rare, but it should be included among differential diagnoses for gross hematuria in patients with a clinical history of thyroid carcinoma.
我们报告一名73岁患有晚期甲状腺乳头状癌的女性，她主诉肉眼血尿。我们发现了一个膀胱肿瘤，并认为它是其症状的病因。该肿瘤的膀胱镜检查结果不寻常，有肿瘤周围血管形成。膀胱肿瘤的病理检查结果与甲状腺乳头状癌转移相符。因此，我们确定甲状腺癌转移至膀胱是我们患者血尿的病因。甲状腺癌转移至膀胱极为罕见，但在有甲状腺癌临床病史的患者出现肉眼血尿时，应将其纳入鉴别诊断范围。
