“MK,” a man aged 67 years, presented with fatigue and nausea to his primary care physician. 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.
