Urothelial carcinoma of the bladder with cutaneous metastases after robot-assisted radical cystectomy. Case report.

Bladder cancer is one of the common urologic malignant diseases. Cutaneous metastasis of bladder cancer is rare, with only a few case reports. The pattern of metastasis from bladder cancer is not well described. We report a patient with muscle-invasive bladder cancer who developed skin metastases after neoadjuvant chemotherapy and robot-assisted laparoscopic radical cystoprostatectomy. Skin metastases were confirmed histopathologically by skin biopsy. This case reminds us of the need to consider the possibility of skin metastasis in the differential diagnosis of skin symptoms in patients with malignant diseases.
