Balanitis xerotica obliterans involving anterior urethra

Balanitis xerotica obliterans (BXO) is known to affect the urethral meatus, glans, and prepuce. We describe a case of biopsy-proved BXO that involves not only the usual areas but the anterior urethra as well. Of added interest is the subsequent development of squamous cell carcinoma in the fossa navicularis. The literature is reviewed.
