The treatment of tinea cruris is to choose antifungal drug treatment, and should be treated with foot treatment. If the patient has only papules, erythema and desquamation, they can be treated only with antifungal ointment, such as clotrimazole ointment and terbinafine ointment. If the patient has secondary eczema, the external compound preparation can be selected for treatment, such as compound ketoconazole ointment for external application. If the patient has obvious local itching accompanied by erosion and exudation, it can be wet applied with boric acid solution or ethacridine solution, and treated with antifungal ointment after the skin lesions are dry. In addition, attention should be paid to the disinfection of underwear and ironing of underwear.
