摘要


發生於膀胱之嗜鉻細胞瘤是很罕見的,佔所有膀胱腫瘤的0.060%,症狀上最多以高血壓、血尿、心悸、尿後昏厥來表現。這72歲的病人因血尿而於電腦斷層檢查中發現膀胱有一個2×2×2立方公分多的腫瘤,接受經尿道膀胱腫瘤刮除手術,經病理診斷上特殊染色S-100及chromogranin A,確診爲副神經瘤,於治療六個月後膀胱鏡追蹤無復發跡象。

Paraganglioma of the urinary bladder is rare, comprising less than 0.06% of all vesical tumors. The most common symptoms include hypertension, hematuria, palpitation, and postmicturition syncope. A 72-year-old man without a history of hypertension presented with painless gross hematuria and acute urine retention. Computed tomography revealed a solid lesion measuring 2cm×2cm×2cm with muscular invasion of the right lateral wall of the urinary bladder. Transurethral resection was performed. Immunohistochemical studies revealed positive staining for S-100 and chromogranin A, findings consistent with the features of paraganglioma. At 6- month follow-up, cystoscopy revealed no disease recurrence.
