Trichophyton mentagrophytes genotype VII dermatophyte terbinafine inflammatory lesions hair loss molecular identification TMVII

TLDR Trichophyton mentagrophytes genotype VII is a sexually transmitted fungus causing skin issues, mainly among men who have sex with men in Europe, and requires quick treatment.

The article discusses the emergence of Trichophyton mentagrophytes genotype VII (TMVII) as a sexually transmitted dermatophyte, particularly affecting men who have sex with men (MSM) and those with high-risk STD profiles. Recent studies from France and Italy report 41 new cases, highlighting the potential for local transmission in Europe. TMVII infections often present as highly inflammatory lesions, which can lead to misdiagnosis and delayed fungal treatment, potentially causing scarring or hair loss. The article emphasizes the importance of awareness and surveillance to reduce diagnostic delays and prevent further spread, recommending molecular identification and treatment with terbinafine.
