title: An unusual differential diagnosis of penile warts: metastases from rectal carcinoma.
abstract: Patients with penile lesions, such as virally induced papillomata, frequently present to genitourinary medicine clinics and general practitioners. Their diagnosis is usually based on clinical observation and biopsy is not generally undertaken. Penile lesions may rarely have a more sinister aetiology and represent metastatic spread from solid tumours arising at distant sites. Penile metastases arise most frequently from genitourinary cancers (prostate, bladder and kidney), but may also arise from tumours of the large bowel; other primary sites are extremely uncommon. We report the case of a patient presenting with penile metastases from rectal carcinoma arising during third-line chemotherapy for metastatic disease.
