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

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

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

Treatment is with topical antifungal medications and is particularly effective if symptoms have recent onset. Prevention of recurrences include treating concurrent fungal infections and taking measures to avoid moisture including keeping the groin region dry.
