Kerion-like lesions following an autoinoculation event in patient with chronic onychomycosis – Case report

Abstract

We report a case of a 75-year-old male with suspected onychomycosis of the right hand and both feet who also developed kerion-like changes in the skin of his head and neck after recent inguinal hernia surgery. A mycological examination revealed the presence of Trichophyton rubrum in all affected sites. Treatment with oral terbinafine and topical isoconazole nitrate was started, resulting in a significant improvement in skin lesions. The case we present underscores the possibility of autoinoculation transmission of dermatophytes and the need for a careful evaluation of the coexistence of mycoses at different anatomical sites.
