Tinea Cruris

Tinea Cruris (股癬), also known as jock itch, crotch itch, or ringworm of the groin, is a common fungal skin condition in the groin, also termed inguinal, area. This fungus can affect the upper inner sides of the thighs, the genital area and may extend to the abdomen and buttocks, causing red, painful, and itchy rashes. 

Causes of Tinea Cruris

Tinea Cruris is caused by the fungus known as dermatophytes. These fungi thrive in warm, moist environments, such as the intertriginous areas, and can spread through direct skin contact or by sharing contaminated towels or clothing. 

Symptoms of Tinea Cruris

Symptoms of Tinea Cruris may include: 

• Red rashes in the groin or inner thigh 
• Flaky or scaly skin around the rash 
• Pain or itching 
• The rash may ulcerate or become inflamed or secondarily infected (bacterial) 

Risk Factors for Tinea Cruris

Anyone can develop Tinea Cruris, but the risk is higher in: 

• Males, particularly young men 
• Individuals with diabetes or immune system disorders or on immunosuppressive therapies 
• Those who sweat excessively or work in humid environments 
• Overweight individuals, due to increased friction and moisture in the groin 
• People who frequently wear tight clothing or athletic gear 
• Pregnancy 

Diagnosis of Tinea Cruris

Doctors typically diagnose Tinea Cruris by examining the skin rash. In some cases, they may scrape off a small sample of the skin and examine it in a lab to confirm the diagnosis. 

Treatment for Tinea Cruris

Tinea Cruris is usually treatable with antifungal creams or ointments, which kill the fungus and prevent further growth. In severe cases, prescription oral antifungal medication may be necessary. 
During treatment, it is important to keep the affected area dry and clean and avoid wearing tight or damp clothing. 

Prevention of Tinea Cruris

Preventative measures for Tinea Cruris include: 

• Keeping the skin dry, especially around the groin and inner thighs 
• Wearing loose cotton underwear to help absorb sweat and keep the skin dry 
• Avoiding sharing towels or clothing 
• Wearing sandals in public showers or changing rooms, avoidance of walking barefoot to avoid getting fungal foot infections 
• Bathing regularly with antifungal soap 
• Using aluminium-based antiperspirants if you have a problem with excessive sweating 
• Prompt treatment of close contacts or family members who have fungal infections of skin and skin appendages 

Tinea Cruris is a common and treatable condition. If you experience symptoms of tinea cruris that do not improve, it's advisable to seek medical advice promptly to prevent worsening of the condition.
