Kerion Celsi is an inflammatory presentation of tinea capitis, caused by a hypersensitivity reaction mediated by T lymphocytes of the dermatophyte in hair follicles. 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.
