Genital ulcer

A genital ulcer is an open sore located on the genital area, which includes the vulva, penis, perianal region, or anus. Genital ulcers are most commonly caused by infectious agents (fungal infections, secondary bacterial infections, or sexually transmitted infections such as genital herpes, syphilis or chancroid). However, this is not always the case, as a genital ulcer may have noninfectious causes as well.
