[Metastatic penile tumor from lower pharynx: a case report]

Area of Science:

• Urology
• Oncology
• Pathology

Background:

• Metastatic tumors to the penis are exceptionally rare, with fewer than 100 cases documented globally.
• Penile metastases typically originate from primary tumors in the prostate, lung, or colon.
• Metastasis from the pharynx to the penis has not been previously reported.

Observation:

• A 70-year-old male presented with urethral induration.
• The patient had a history of squamous cell carcinoma of the lower pharynx.

Findings:

• Pathological diagnosis confirmed metastatic penile tumor originating from the lower pharynx.
• Irradiation therapy resulted in a partial response in tumor size.
• The patient succumbed to widespread metastases within four months of diagnosis.

Implications:

• This case represents the first reported instance of penile metastasis from lower pharyngeal squamous cell carcinoma.
• Highlights the importance of considering rare metastatic origins in penile lesions.
• Underscores the aggressive nature and poor prognosis of such advanced metastatic disease.
