"MK," a man aged 67 years, presented with fatigue and nausea to his primary care physician. Routine blood tests showed a stage III acute kidney injury and the patient was admitted urgently into the hospital for investigation. On initial assessment by the nursing staff, with urine dip and bladder scan, he was found to have a large fungating mass on his penis. Upon further questioning, MK reported having had trouble with urination for a number of years and that he had been concealing the mass for at least 1 year due to embarrassment. He required a suprapubic catheter as the mass had completely obstructed his urethra. Clinical examination revealed that the external component on the penile shaft was entirely destroyed by the tumor, with extension deep into the entirety of the scrotum, and perineal soft-tissue invasion was also apparent. CT staging scans confirmed the primary tumor and a suspicious left 1.2-cm inguinal lymph node but no distant metastases. MRI of the pelvis revealed complete replacement of the penis with tumor as well as invasion into the scrotum and bilateral groin soft tissue; additionally, early pubic bone invasion was present, with left groin lymphadenopathy. Biopsy verified squamous cell carcinoma of the penis, and discussion with the multidisciplinary team uroradiologist confirmed bony invasion.
