Tinea corporis
Tinea corporis, or infection on non-hair-bearing skin, may have a variable appearance, depending on the extent of the associated inflammatory reaction. It may have the typical annular appearance of "ringworm" or appear as deep inflammatory nodules (on the scalp known as a kerion) or granulomas.
Treatment of Tinea Corporis
ntil recently, griseofulvin was the recommended therapy for dermatophyte infection of the nails. However, despite prolonged treatment, cure rates were poor. Itraconazole given as either continuous daily therapy (200 mg/d for 3 months) or pulses (200 mg twice daily for 1 week per month for 3 consecutive months) has been shown to be a safe and effective therapy. Itraconazole has the potential for interactions with other drugs requiring the P450 enzyme system for metabolism.
Similarly, terbinafine (250 mg/d for 3 months) has shown similar cure rates. Only limited data are available on the dosing and effectiveness of the newer antifungal agents in tinea corporis, tinea cruris, and uncomplicated tinea pedis.
