Abstract

A 7 year-old boy visited our hospital with a 2 week history of inflammatory, pustular, tender patches and plaques on the right scalp and face area. He had been treated with topical steroid and antibiotics in a private clinic. In a KOH smear mount, multiple hyphaes and spores appeared on stratum corneum of the outer root sheath layer of his hair. The diagnosis of kerion celsi induced by dermatophytes was made. The patient was treated with oral griseofulvin, and on the 2nd day after starting treatment, multiple erythematous and tendered subcutaneous nodules occurred on his shin. A photosensitive dermatitis like lesion also occurred on his periorbital area. Griseofulvin changed to terbinafine. On the 6th day after treatment, the skin lesions on his face and scalp had improved, as had his shin lesions. The interest of this case lies in the unusual association of kerion and erythema nodosum, of which only eleven cases have been reported in dermatologic literature, and all cases were kerion induced Trichophyton species.
