Abstract

A 41-year-old woman presented with a pruritic rash on the face that was of 3 months duration. During that time, it had been successively misdiagnosed as psoriasis vulgaris, systemic lupus erythematosus, facial dermatitis at other hospitals, and had been treated with agents that included acitretin and prednisone. Finally, fungi were found in the lesions by optical microscopy, and the fungal culture was positive for Microsporum gypseum, and was diagnosed as a Microsporum gypseum infection. The lesions eventually cleared completely after 8 weeks of antifungal treatment.

Summary

Introduction

A 41-year-old woman presented with a pruritic rash on the face that was of 3 months duration. The rash transiently improved with the use of these medications but flared with any attempt to discontinue treatment. Physical examination revealed a 25-cm diameter circle of erythema with central clearing, atrophic patch with telangiectasis, pustular and slightly scaly plaques with central clearing at the lateral margin of the face was visible, excoriations and mild inflammation were noted around all affected areas (Fig. 1). A 10 percent potassium hydroxide examination of the lesions revealed numerous branching, septate hyphae, and the fungal culture was positive for Microsporum gypseum.
