Bladder squamous cell carcinoma (SCC) may lead to gross hematuria. However, the metastasis of head and neck cutaneous SCC to the urinary bladder has not been described in literature. Nowadays, noninvasive methods such as embolization, are considered as an appropriate choice for controlling life-threatening hematuria in patients with high operative risk. However, few reports exist on the effectiveness of this approach in managing the hematuria secondary to metastatic bladder SCC. Here we report a case of bladder SCC originating from the forehead cutaneous SCC. An 83-year-old man, a known case of forehead cutaneous SCC with distant metastasis, referred to our clinic with a chief complaint of hematuria. Pathology confirmed the diagnosis of metastatic urinary bladder SCC. Angiography and embolization were undertaken and resulted in complete alleviation of the symptoms. The recurrence of hematuria or embolization-related complications were not observed during 3-month follow-up. Selective embolization of the bilateral internal iliac artery is a safe and efficient procedure for controlling severe hematuria in patients with primary or metastatic bladder SCC.
