Common groin eruptions: diagnosis and treatment.

Most common groin lesions are caused by fungi, bacteria, psychogenic factors, viruses, parasites, or tumors. The workup of all patients with an inguinal skin disorder should include a history, physical examination, microscopic examination and culture of scrapings from the eruption, and examination of the eruption by Wood's light. Agents useful in treating groin lesions include topical and systemic corticosteroids and antibiotics, antipruritic agents, Burow's solution, and lindane. Prolonged use of high-potency topical corticosteroids can be deleterious.
