Tinea Corporis

Tinea corporis occurs most often on the torso of elderly persons. It commonly appears as an annular plaque with a rim of scaly erythema (Figure 1). Occasionally, tinea corporis manifests with polycyclic annuli (Figure 2) or with nummular plaques, which mimic nummular dermatitis. The examination of a potassium hydroxide preparation can establish the diagnosis. Tinea corporis can be treated effectively with a topical antifungal agent.
