A case of synchronous double primary cancer of the penis and urinary bladder.

ABSTRACT

Multiple primary cancers are the occurrence of more than two cancers of different origin in an individual. Penile cancer is a rare disease, and finding it combined with other cancers is even rarer. A 64-year-old man with a painful penile mass was referred to us from a primary urological clinic. We performed a biopsy of the penile mass and the histology revealed a well-differentiated squamous cell carcinoma. Abdominal computed tomography showed a localized bladder tumor with inguinal lymphadenopathy. The patient underwent a partial penectomy, transurethral resection of the bladder tumor and inguinal lymph node dissection. The histology of the bladder tumor was high-grade papillary carcinoma, and that of the lymph node was squamous cell carcinoma. The penile and bladder tumors were in stage II (T1N1M0) and stage I (T1N0M0), respectively. We successfully treated the patient with adjuvant radiotherapy and systemic chemotherapy.
