Answer

Circinate balanitis, consisting of small shallow painless ulcers of the urethral meatus or the glans penis (see the images below), is characteristic. The condition is characterized by circinate or gyrate white plaques that grow centrifugally and eventually cover the entire surface of the glans penis. The penile shaft and scrotum can be involved. On an uncircumcised penis, the lesions typically remain moist; on a circumcised penis, they may harden and crust, causing pain and scarring in 50% of patients. [68]
