Jock Itch is a fungus infection of the soft skin of the upper thigh region, which tends to occur more frequently in males. The medical name is tinea cruris. It can also affect the buttock crease. Various dermatophytes and candida species are the pathogens for this condition. Here is an jock itch picture.
Sweating, lack of hygiene and demanding sports activities tend to lead to skin breakdown and fungal infections in the “intercrural area”, which is the medical term for the skin-folds in the upper thigh region. Obesity is another high risk factor for developing jock itch.
Often tinea cruris starts with a red flat skin spot in the intercrural area that is irritated and tender when clothing rubs on it. The lesion gets slightly swollen and becomes more prominent than the surrounding healthy skin. Untreated it clears up in the center and subsequently assumes a ring like shape that grows in the periphery. When the skin breaks down, it can get super-infected with skin bacteria and candida species. The scrotum usually does not get involved with tinea cruris, but when yeast infections (candidiasis) super-infect the open sores, the scrotum commonly gets infected as well.
Treatment of Jock Itch
When it is recognized early, topical therapy is usually very effective. Topical antifungal lotions or creams as described under treatment of tinea corporis are used. For deeper, more difficult to treat infections oral medication likely has to be considered. The duration of the oral medication may have to be for 3 to 6 weeks. In complicated cases, where superinfection with Candida albicans is noted, this might have to be treated with a course of itraconazole (brand name: Sporanox) and 200 mg once daily for 1 month might be required. Discuss this with your doctor.
