Background. Penile metastasis is a rare event, and cases involving penile metastasis of primary lung cancer are extremely rare. Case. We report the case of a 62-year-old man. An abnormality was pointed out on a chest X-ray obtained during postoperative follow-up after stomach cancer treatment. He was diagnosed with lung adenocarcinoma (cT2aN3M0 Stage IIIB), and received chemotherapy. At 5 months after the initiation of chemotherapy, he visited the urology department with a painfully enlarged penis and dysuria. We suspected penile metastasis because FDG positron emission tomography (FDG-PET) showed an abnormal uptake in the penis. A biopsy of the corpus spongiosum revealed adenocarcinoma (the same as the primary lung cancer). His symptoms improved following percutaneous cystostomy, and he underwent chemotherapy again without any major adverse events. He died of lung cancer 5 months after the appearance of penile metastasis. Conclusions. Percutaneous cystostomy was safe and effective for managing the symptoms of penile metastasis.
