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