Dermatophytosis in healing herpes zoster lesions

Fungal infection of the face is frequently misdiagnosed, since the typical ringworm, erythematous, slightly scaling, indistinct borders are only uncommonly seen on the face. Herpes zoster is a common infection caused by the varicella-zoster virus that transmits varicella (chickenpox). Granulomatous reactions such as granuloma annulare, pseudolymphoma, sarcoidal reaction, and eruptive keratoacanthoma have been described in herpes zoster scars. We describe here the first reported case of dermatophytosis occurring in healing herpes zoster lesions. This condition has not been previously reported.
