Abstract:
A 65-year-old man presented with metastatic squamous cell carcinoma in the inguinal lymph nodes from an unknown primary tumour. The initial work-up lacked clinical examination of the glans penis, in part due to the patient having phimosis. More than a year after presentation, a primary tumour, located distally on the penis, was diagnosed. A discussion of urethral carcinoma as well as inguinal lymph-node metastasis of unknown primary tumour is presented.
