Cutaneous metastasis of bladder urothelial carcinoma; A rare conditions

Abstract

Cutaneous is an extremely rare metastatic area of bladder urothelial carcinoma. Pure cutaneous metastasis without systemic metastasis is very rare and less than ten cases have been reported in the literature. Our patient had various lymphatic fistulas to her skin due to pelvic lymphadenectomy and radiotherapy in her previous cervical cancer. We believe that the most probable mechanism underlying our patient's cutaneous metastasis is a lymphatic spread via those lymphatic fistulas. Immunotherapy is a very important option for patients who cannot receive cisplatin. This is the second case in the literature to apply immunotherapy in the setting of cutaneous metastasis of bladder cancer.
