The early clinical recognition avoids invasive procedures. Hyperleukocytosis/ leukemoid reactions are hematologic reactional responses that may result. The most frequently involved agents are Trichophyton verrucosum, Trichophyton mentagrophytes, Microsporum canis and Microsporum gypseu. The clinical spectrum is widely variable.porDermatophyte hypersensitivity reactionKerion Celsitinea capitisjournal article
