Tinea Types: Common Dermatophyte Infections Case 7 Atypical Tinea Corporis

By Dr Robert P. Blereau.

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 clearing. 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.
