Tinea Cruris

Tinea cruris, also known as jock itch, is a fungal infection of the skin that affects the groin area, thighs, and buttocks.

Causes and Risk Factors

• Tinea cruris is caused by a type of fungus called dermatophytes, which thrive in warm, moist environments.

Diagnosis

Tinea cruris is typically diagnosed based on a physical examination and medical history.

• A healthcare professional may perform a potassium hydroxide (KOH) test to examine the skin scrapings under a microscope.

Treatment for tinea cruris typically involves topical antifungal medications, such as:

• Clotrimazole (Lotrimin)

In severe cases, oral antifungal medications may be prescribed.
