Cause of Pruritus Scroti
Jock itch is a common, itchy rash of the groin. It can produce a very intense itch and is associated with a red or pink rash involving the groin folds and genitals. Jock itch is primarily a skin condition in men because of anatomic structures unique to males, the male genitalia.
The symptoms and signs of jock itch may come and go, and many cases of jock itch resolve spontaneously without any treatment. Jock itch is primarily seen in the groin, although it may spread to the inner thighs, genitals (including penis, scrotum, labia, and vaginal opening), and anus.
