Abstract

A 68-year-old man was diagnosed with non-muscle-invasive bladder cancer and underwent transurethral resection of the bladder tumor (TURBT) in June 2014. The pathological diagnosis was urothelial carcinoma (UC), Grade 2, pT1. He was treated with intravesical bacillus Calmette-Guérin (BCG) instillation after TURBT. In February 2016, he received anti-tuberculosis treatment for systemic BCG infection, and tuberculosis treatment was continued. In September 2018, he presented with bilateral scrotum swelling and underwent bilateral orchiectomy following a diagnosis of antituberculotics-resistant epididymitis. The pathological findings were metastatic UC of the bilateral epididymis and testis. One months later, fluorodeoxyglucose-positron emission tomography/computed tomography showed para-aortic lymph node and peritoneal metastases. He was treated with chemotherapy of gemcitabine and cisplatin. We herein report a very rare case of synchronous metastatic UC of the bilateral epididymis and testis after intravesical BCG treatment.
