Tinea Cruris, commonly known as jock itch, is a fungal infection that affects the skin in the groin area. It is caused by dermatophytes, a type of fungus that thrives in warm, moist environments. Symptoms include itching, redness, and a rash that may spread to the inner thighs and buttocks. This condition is more common in males and can be triggered by factors such as excessive sweating, tight clothing, and poor hygiene. Treatment typically involves antifungal creams or powders, and maintaining good hygiene can help prevent recurrence.
