A 33-year-old male patient visited Primary Care with an itchy, scaly inguinal rash, exacerbated by warm weather and exercise. The patient was treated for tinea cruris. Tinea cruris, commonly called “jock itch,” is a fungal infection affecting the groin and medial thighs. Tinea cruris presents as an erythematous, confluent, pruritic, and scaling rash. It commonly affects adult men and athletes. Individuals with tinea cruris may also present with tinea pedis (fungal infection of the feet). The diagnosis is usually clinical, and can be confirmed by KOH test if necessary. Tinea cruris is treated with imidazole or allylamine topical antifungals. Oral antifungals are indicated for severe or recurrent infections. If tinea pedis is present it should also be treated in order to prevent future autoinfection. Over-the-counter antifungal powders may be recommended as prophylactic therapy.
