Surgical Treatment of Adrenal Gland Metastasis Originating from Small Cell Carcinoma of the Urinary Bladder

We report a rare case of a solitary adrenal metastasis from small cell carcinoma of the urinary bladder that was successfully treated with surgical resection. A 71-year-old man was suffering from bladder tamponade for hematuria. Computed tomography (CT) revealed a bladder tumor at the left wall. The patients underwent radical cystectomy. Histopathological results were obtained in small cell carcinoma of the bladder with muscle invasion. Thus, he received two courses of adjuvant etoposide and cisplatin chemotherapy, followed by the regimen for small cell lung cancer. Seven months after surgery, follow-up CT showed a gradually enlarged mass enhanced heterogeneously in the right adrenal gland. There was a solitary adrenal metastasis without any other metastasis; therefore, we performed right laparoscopic adrenalectomy. The patient has remained uneventful for four years after the adrenal gland surgery. For patients who have a solitary adrenal metastasis, adrenalectomy may provide a survival benefit.
