The clinical presentation of invasive dermatophytosis often mimics other more common skin diseases. We report a case of severe deep dermatophytosis caused by Trichophyton mentagrophytes initially interpreted as herpetiform rash. The diagnosis was established based on fungal culturing and molecular detection using RT-PCR in addition to response to treatment using oral terbinafine. Our case emphasizes the importance of fungal testing at an early point to accelerate diagnosis and initiation of correct treatment. 2012 Elsevier Ltd. All rights reserved.
