A Canadian man contracted a rare fungal skin infection caused by Trichophyton mentagrophytes genotype VII during a trip to Mexico, likely through sexual contact. The infection presented as deep, painful lesions in the genital area that didn’t respond to typical treatments and required 10 weeks of oral and topical antifungal medication to cure. This is the first confirmed case in Canada and highlights the importance of doctors being aware of sexually transmitted fungal infections, especially in patients with unusual rashes that don’t improve with standard treatments.
