Overview
Patients are usually well-appearing in dermatophytosis. The skin is characterized by erythematous, papulosquamous, annular, well-circumscribed, superficial rash with central clearing which may be located on the scalp, neck, trunk, extremities and groin. Abnormalities of the head/hair may include, dry scaling, which may be similar to seborrheic dermatitis; black dots, which are areas of broken hair on a scaly surface; smooth areas of hair loss. Neck in tinea corporis may show, red, itchy, scaly, circular skin rash and cervical lymphadenopathy. Genitals may be involved in tinea cruris and examination may show pustules and vesicles at the active edge of the infected area along with maceration. Hands in tinea mannum may show dry and hyperkeratotic palmar surface. Feet in tinea pedis may show fissuring, maceration, and scaling in the interdigital spaces of the fourth and fifth toes.
