A new lesion recently arose on the right flexor forearm ofa 67-year-old man. The 1-cm, pruritic, pink, circular, slightlyraised lesion was perfectly homogeneous with no centralclearing.Tinea corporis was suspected; however, the lesion'selevation (about 2 mm) and the absence of central clearingwere unusual features for ringworm. A potassiumhydroxide evaluation was performed and confirmed thediagnosis of tinea corporis.Miconazole cream was applied twice daily for 3 weeks.The patient's fungal infection resolved completely.
