Abstract

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 pedis and onychomycosis. But tinea capitis caused by T. rubrum is rare. Tinea capitis is uncommon in an adult. We report a case of tinea capitis caused by T. rubrum in an 81-year-old woman. She presented with localized asymptomatic well-demarcated thick scaly erythematous patches on the fronto-vertex scalp for 6 months. She was diagnosed as seborrheic dermatitis in local clinic and was treated with topical steroid. However, the lesion was not improved and spreading. Culture from scalp lesion of patient was grown on Sabouraud's dextrose agar and showed typical whitish cottony colonies of T. rubrum. She was treated with 200 mg of oral itraconazole daily for 8 weeks. The skin lesions improved 8 weeks after treatment, and recurrence has not been observed.
