Tropical climates and summer months in temperate regions appear to promote higher rates of this infection. Clinical manifestations Tinea cruris presents with sharply demarcated lesions with a raised erythematous margin and thin dry epidermal scaling. Papulovesicular lesions may also be present but pustules such as those caused by Candida are very unusual. Lesions classically involve the genitocrural area and medial upper thigh in a symmetric fasion, but asymetric involvement may occur. Patients complain initially of intense pruritus, but the lesions will become painful if maceration and superinfection occur.
Topical therapy is usually enough to cure tinea cruris.
Drugs formulated in powders or minimally occlusive cream bases are preferred. Recommended regimens are the same discussed for Tinea corporis . Rates of relapse for this infections are very high, therefore hygiene measures are crucial for long term success. They should include thorough drying, the use of well-ventilated clothing, and separate towels for the groin area. As mentioned above, tinea cruris is just an anatomic variety of tinea corporis, therefore pathologic and diagnostic considerations are the same.
