Kerion celsi is an inflammatory type of tinea capitis. It is present as boggy mass studded with broken hairs, oozing purulent material from follicular orifices. This infection is caused most commonly by zoophilic or geophilic pathogens. Trichophyton(T.) rubrum is an anthropophilic dermatophyte that is found all over the world. It has become one of the most important causative agents in tinea unguium and tinea pedis. But, Kerion celsi caused by T. rubrum is rare. Kerion celsi is ucommon in adult. We report a case of kerion celsi caused by T. rubrum in a 91-year-old woman. She presented with localized tendererythematous plaques with abscess on the frontal scalp. A fungal culture from tissue of the lesions was grown on Sabouraud``s dextrose agar and showed typical whitish cottony colonies of T. rubrum. She was treated with 200mg of oral itraconazole daily for 3 months. The skin lesions improved 1 month after treatment, and recurrence has not been observed.
