Cat's curse: a case of misdiagnosed kerion

Kerion is an inflammatory type of tinea capitis which can be mistaken for bacterial infection or folliculitis as both conditions display similar clinical features. It occurs most frequently in prepubescent children and rarely in adults. We report a 26-year-old woman who presented with multiple tender inflammed nodules on her scalp. Her condition was misdiagnosed as bacterial abscess and treated with multiple courses of antibiotics without improvement. Later, her condition was re-diagnosed as kerion based on clinical appearance, history of contact with infected animal and Wood's lamp examination. symptoms and lesions resolved completely with systemic antifungal treatment leaving residual scarring alopecia. The delay in the diagnosis and treatment of this patient resulted in permanent scarring alopecia.
