Tinea cruris is a common, contagious, superficial fungal infection of the groin region. It occurs predominantly in men and in hot‑humid climates.

Typically, over the upper inner thighs, an itchy, red, raised rash with a scaly, curved border appears. It is often associated with athlete’s foot, fungal nail infections, excessive sweating, and sharing of infected towels or sports clothing. It is uncommon in children.

Its appearance may be similar to other rashes that occur in skin folds, including candidal intertrigo, erythrasma, inverse psoriasis, and seborrhoeic dermatitis.

Treatment with topical antifungal medications is especially effective when symptoms have a recent onset. Prevention of recurrences includes treating concurrent fungal infections and taking measures to avoid moisture, such as keeping the groin region dry.
